Anyone else notice this?
It roasting today and I've noticed spotting on a few windows today.
It's upset me a bit lol, my TDS is zero and technique flawless of course.
Never noticed when it's cold, hope it's just the sun.
-
When cleaning in hot sunlight, clean the frames first on all the windows. 90 percent of the time the frames will be oxidizing in the sun, and those spots are a result of that. Once frames are done, do the glass only.
Also flow is king, high flow on hot days is really the only way.
-
Agree with Mark. I set my flow higher on hot sunny days
-
Just sack it off and get the vino out .
-
I decided to work half day today as ive only 6 houses left this week and they can wait till morning.
So, gone to lakeside pub and phone wive who was in town to meet me with my littlest and we had a nice drink n enjoying this glorious sun before it disappears

I doubt paedos are stalking a window cleaning forum
Though there are some dodgey characters on here ;D
-
Did you actually give them a rub to see if its your doing, some windows will have ingrained spotting that shows up better
in full sun, dodgy rubber seals can also give more problems in full sun as the frames can expand slightly in the heat allowing more water to get in behind them and drip onto the glass after you have finished.

You did say you’ve been doing 1st cleans all day pal , maybe they’re just filthy and need a good flushing out 👍

I had a nursing home yesterday that I do in and out, I did the outside and spent longer on the top frames so that when I went back later to do the insides they would look perfect.
I went back later and still found some spots. Not many but 2-3 windows out of 48 still enough to annoy me.
Its slightly diss-heartening to try your best and still find imperfections, makes you wander if your leaving spots everywhere you go?
I think I will try the "all frames first then glass" method.

The winters may be harsh but at least they are easy to clean windows in hey!

I did a nursing home yesterday too, second clean. Flew through the outsides, was expecting some spotting tbh but they were dry by the time I cleaned the internals and all completely spotless.
Out of interest, why do you return the next day to clean the insides? 48 windows could be cleaned in/out the same day surely? The home that I cleaned was 120+ windows and I was done there before dinner.

I had a pressure washing job on today. Made the fatal mistake of parking the pressure washer too close to the conservatory.

Oh dear slacky , how u gonna sort that out?

Insurance.

Forget hot water just giving you comfort in the cold weather this hot weather is when I find it comes into its own,I cleaned a house today on 28degree heat my water was at 55 degrees the Windows were dry in minutes in some cases seconds with just a few spots left,you could almost check as you go it was leaving such little amounts of water behind on the glass.

I didn't mate, if you re-read my post it says I went back later.
As you know if you do nursing homes t-time is a good time to clean inside as they are mostly around the dinner tables and not so much in the way.
-
Another reason for getting spots in the warm weather is that the water has dried before its washed the contaminates away. A window cleaner in Cyprus says they have to spray the window first and cool it down before they can clean it. So you need to rinse a lot more when cleaning those sun facing windows.
And of course you also need to use pure water rather than 'thats good enough' pure water.
-
a very high flow helps in warm weather.(my water was at 55c-60c too which helps a lot)
most of my jobs today were 2 monthly with a fair amount of bird muck,snail trails and little yellow spots on the windows...very hot water just melts the marks off... :)

yep i agree sean.full sun will show up EVERY little mark on the glass both outside and inside....
dont worry lads itll be raining again next week... ;D

my water is at 004 at the moment and windows are drying spot free.......ill be adding another fresh vessel tomorrow though(double DI)....

If your hot your heater will be working far hotter or should be at the moment,my water at the brush today was really hot I stuck my hand over the water today and it was almost unbearable to touch.

My mistake, I misread your post.
I just do internal communal areas/corridors etc on the few that I clean, I don’t and won’t go into residents rooms.

Mine was that hot had steam coming off the glass had to turn it down to minimum by lunch time and to be fair it was still to hot could have turned it off really

I decided to work half day today as ive only 6 houses left this week and they can wait till morning.
So, gone to lakeside pub and phone wive who was in town to meet me with my littlest and we had a nice drink n enjoying this glorious sun before it disappears

Cause mate I dont have to worry about spotting in the sun as im chilling in the sun instead.
Work in the rain n rubbish weather so im all upto date on my work, so on days like today I can choose to finish at lunch n spend it with the family.
On track with the thread and someones post about needing zero parts per million is rubbish. Ive worked half a day today in this heat and my water is hot at 65 degrees and tds of 006 and theres no spotting at all. As someone else as mentioned, hot water users will have much quicker drying times and so i can check before I leave.
Working in full sun is no different to working in no sun as far as spotting is concerned, provided your not conserving water and only trickling water out when your rinsing ;D but for me and my 6jets with fast flowing hot water, slow is certainly not what i descibe it.
-
If your hot your heater will be working far hotter or should be at the moment,my water at the brush today was really hot I stuck my hand over the water today and it was almost unbearable to touch.
My water in tank was over 65 degrees this morning in an insulated tank. I went out at 9,30pm to see if i need to top my tank up for some first cleans tomorrow, I could feel the heat come out the tank and so I checked the temp. It was 47 degrees and probably had about 300 ltrs or so left in tank (its hard to guage how much water is in a tank) and so I wont put the immersion on till maybe midnight

Its Nathan, the only guy on the planet able to get water to over 60degrees in a few hours with a 1kw heater who one day will have turned tea total and vegan the next will be sitting in a pub with a drink, I'm just wondering how big the six properties
are when its going to take him 300lts of water and 4 hours to clean them, normally that would be 15 to 20 detached with conny's, lol

-
That said I do agree with him on not needing the water to be at zero because of the higher temps, if you are getting spotting then
the first thing you need to do is check that its not ingrained and therefore impossible to remove, next check the pattern of the
spotting as this will tell you whats causing it, runs of sptting down the glass will be water dripping from somewhere like vents
dodgy openers or seals, spotting all over the glass in different amounts will tend to be the fault of the shiner, cleaning too quick,
not using enough water, flow too low and so on.
Spotting is easier to see in full sun but you can be sure if you are getting it in full sun you will also be getting it when its not as easy to see.
-
It still amazes me how some people clean with 4 or 5 or even 10 tds, might be ok for hydrophilic glass in the shade, but combine hydrophobic in hot direct sunlight at 10 tds then really, your asking for issues. I always keep mine at 000.
Really need to be on top of your quality control at this time of the year, especially if you are having a major push forward with new cleans, do em all wrong and you might as well say, we are crap at what we do, lets announce that so everyone knows. 8)
I would never try to do 10 1st cleans a day, max per day on 1st cleans for me is probbably 4.

Haha love the walty mitty photo, i had unpleasure of watching the film but it turned out really good for walter, just saying ;D
Obviously aint going to be using all the 300 ltrs this morning, i just didnt know how much wateri had left for today before I checked so I didnt need to top up.
Water temp, started last night in the forties and turned immersion on at midnight till 8.30 this morning, though should have turned it off earlier as the water is 75.
(http://www.cleanitup.co.uk/smf/1524210360_Screenshot_20180420-084042.png)
The starting temp is really high to begin with, in an insulated tank and the immersion is already hot so thered no warming up time required.

Under perfect test conditions, it isnt until a tds of 050 that spotting occurs.
Yes we dont work in test conditions, but once the window is clean and 006 water that im currently using, is left on the glass in full sun or not (it will dry the same either way) will be ok and is ok.
Many use water even above this and once I had a time where mine got upto 015 and was drying ok. If its a problem then all of us who dont sweat about the mysterious magical 000 would be foolish to not take heed and yet our results speaks for itself

Personally Nathan, i disagree.
Why take the chance? If your always cleaning at 000 then your just not going to get issues at all are you.
And if i found anyone using 005 or 010 or even 015 id sack em.
But thats just my opinion.

You’ll get terrible spotting with a TDS like that.

mines been 004 today...no spotting whatsoever....i have added a fresh vessel this afternoon though so itll be back to 000 on monday.....(currently its 002)
anything up to 010 has always been fine for me....

Mine was 015 yesterday, no spotting at all, even in the direct sun. I know this because I cleaned internals on a large place that had dried completely by the time I got inside.
Saying that I changed my resin last night as I had a couple of first cleans to do today (on Dazmonds “Patch” aswell😂) and I wouldn’t want to use that water on first cleans just incase.

Managed to get a bnb for night as well in reeth, so again i dont need to worry about the tds lol.
Its great being your own boss, being upto date on your work and having the freedom to do this.
Anybody work out this way? Wondered what prices you could quote round here

It’s not just about not spotting , the closer to 000 your water is the more aggressive the water is at desolving dirt and the water absorbes it better and quicker if you are using water at anything above 000 the higher the number the lazier the water is at desolving dirt so the more likelyhood of getting spotting increases unless you spend more time scrubbing and rinsing which isn’t cost effective in amount of time taken or the amount of water used : this is the whole reason that pure water is used if it’s above 000 it’s isnt pure

That old wives tale came out back in the early days to help sell wfp, ( remember hungry water lol ) we don't dissolve the dirt
we agitate/loosen it from the glass/frames and then rinse it off.
We filter the water to remove dissolved solids that would be seen on the glass after it dries nothing more, if 000pm was a must have then we would all be in trouble because our cheap tds meters are nowhere near accurate enough to measure it to that exact level.

I'm surprised you still fall and believe in this rubbish reflections you come across as an intelligent person. You use water that is purified to a certain level and that's it. To say at 0ppm your water is "pure" and above is not pure is a silly comment to make, what if you could measure your water with ppb tds meter how pure would your 0ppm now look. Next you'll be saying hot cleans twice as fast ;D
-
It isnt rubbish. Aggressive water is used in manufacturing, and as high quality de ionized water has given up all its free ions any crap that the water comes in contact with the water will absorb it. Its been used in integrated curcuit design for the last 50 years, and it was in fact the key part of making computer chip manufacturing possible as there was no other way of cleaning silicon substrates in an effective enough way. So the invention of DI water in fact enabled computers to go from filling a room to filling a size of your fingernail.

The computer industry uses ultra pure (parts per billion or part per trillion) for no other reason than the removal of as many contaminants as possible from the water, its aggressive nature is due to it having a low PH acidic, luckily for us 0ppm tends to sit around the neutral to only slightly acidic mark so wont do any damage to what we are cleaning, it might absorb salt or calcium slightly better but it certainly wont be to any noticeable degree and a few ppm above zero wont effect this.
-
Parts per billion is marketing jarjon designed to empty the pockets of gullible window cleaners...and its like saying reading your car speed in kmh is superior to that of mph. It makes no difference, the speed is the speed.
If your reader reads 000. Its 000. Doesnt matter if its parts per billion trillion or quadrillion. Zero is zero. It only matters when the reading starts to count up.
Secondly, people in the water purification industry dont measure in parts per million as thats an estimation using a forumla of the calculated conductivity reading and the current kinetic energy of the water ( temperature)
Pure water will have zero conductivity. This is measured in microsiemens and really if you wanted pure accuracy on your pure water you need to be reading in microsiemens.

It still amazes me how some people clean with 4 or 5 or even 10 tds, might be ok for hydrophilic glass in the shade, but combine hydrophobic in hot direct sunlight at 10 tds then really, your asking for issues.
Really need to be on top of your quality control at this time of the year, especially if you are having a major push forward with new cleans, do em all wrong and you might as well say, we are crap at what we do, lets announce that so everyone knows. 8)
I would never try to do 10 1st cleans a day, max per day on 1st cleans for me is probbably 4.
Under perfect test conditions, it isnt until a tds of 050 that spotting occurs.
Yes we dont work in test conditions, but once the window is clean and 006 water that im currently using, is left on the glass in full sun or not (it will dry the same either way) will be ok and is ok.
Many use water even above this and once I had a time where mine got upto 015 and was drying ok. If its a problem then all of us who dont sweat about the mysterious magical 000 would be foolish to not take heed and yet our results speaks for itself
It’s not just about not spotting , the closer to 000 your water is the more aggressive the water is at desolving dirt and the water absorbes it better and quicker if you are using water at anything above 000 the higher the number the lazier the water is at desolving dirt so the more likelyhood of getting spotting increases unless you spend more time scrubbing and rinsing which isn’t cost effective in amount of time taken or the amount of water used : this is the whole reason that pure water is used if it’s above 000 it’s isnt pure
That old wives tale came out back in the early days to help sell wfp, ( remember hungry water lol ) we don't dissolve the dirt
we agitate/loosen it from the glass/frames and then rinse it off.
We filter the water to remove dissolved solids that would be seen on the glass after it dries nothing more, if 000pm was a must have then we would all be in trouble because our cheap tds meters are nowhere near accurate enough to measure it to that exact level.
Don’t think it’s an old wives tale one of my customers is a chemist and took great delight in telling me all the scientific facts as to how it actually does it , if you want to get really complicated you can go into the - 000 scale I thought that was a load of rubbish ionics used to sell systems but according to this guy it’s true and is used in many industries for cleaning surfaces without using any chemicals he did explain it but was way over my head 😂😂😂😂😂

I'm surprised you still fall and believe in this rubbish reflections you come across as an intelligent person. You use water that is purified to a certain level and that's it. To say at 0ppm your water is "pure" and above is not pure is a silly comment to make, what if you could measure your water with ppb tds meter how pure would your 0ppm now look. Next you'll be saying hot cleans twice as fast ;D
Ime not going to get into some scientific debate but it is a fact that this is the case if 000 is taken as pure then 001 is starting to be dirty : yes only slightly I admit but the higher the reading the less cleaning power the water has this is how ppb works do we need water that good to clean windows probably not but will it clean better and quicker yes it will it’s a scientific fact weather ones believe it or not I personally don’t care what ones use if they want to use water with a tds of 100 crack on as it will result in us getting more customers as the finish they get will be very poor there are a number of cleaners in my area who boast that you don’t need water with 000 and they regularly use up to 035 and wonder why we are picking up a large percentage of the customers they won’t accept that there water is a problem but when you look at the properties we clean and then the ones that they do there is a huge difference that’s a fact people do notice it that’s how we get a lot of our work they say why does my neibours windows look so much better than mine you both clean it the same way I then explained it’s about water quality we get around 40% of all new work beacause of this
-
Well all this has been fascinating to read im sure ;D ;D
But these facts and figures do not take into sccount the force in which the water comes into contact with the contaminants on the glass, not the agitation of the brush and certainly not if the water is hot.
So in conclusion, im going to stick with my 14 inch dual trimmed six jetted brush and using hot water slightly above pure with a reading of 006 and be a content little worker ;D ;D
-
I fill my resin vessel pump water through it if it reads zero up to about 10 it gets used end of ;D

I am in full agreement here.
I have picked up work from many other window cleaners in my area, and the biggest issues with them is 1. Tardiness and 2. Rubbish results.
I always always keep my water at 000.
And i keep to my schedual.
And i am reasonably priced for my area, one firm wanted £90 for a 3 bed semi here recenty, and i have watched them work, scubbing and rinsing the same window for 20 mins nearly, complete amateurs.
-
I double di after RO to cover all bases and get everything I can from my resin.
-
Why were you watching them for 20 minutes Marc ?! Have you not enough work to do ;D
Also
•2 - how do you know they charge 90 squids
Just askin like ..... :D

I drove past them on Thursday to a job, did my job then diving onto my next job the same guy is standing there 'rinsing' (this always makes me laugh) the same window i saw him doing 20.mins earlier.
And i know what they charge, because yesterday i got a recommendation from one of my customers,went and did the quote the guy was really happy and as a result i also picked up his neghbour too, he then told me some of the ridiculous prices hes been quoted, and i asked him what company it was.

Fair enough :)

So to clarify, are you simoky saying that spotting on the window is purely down to water tds? That the complaints about previous window cleaners they have tried and the conclusion is down to the water?
Ime I would say not
-
my water was 026 once last year buy mistake and i was cleaning a job the lady came out and said her windows were spotty all over ,i went to have a look as they were allmost completly dry and i couldent see any spots till i went inside ,the windows all sheet on this job to had to squeegee the windows luckly it was a bungalow , checked next door and they were fine ,so it depends on the glass your cleaning,i came home early cleaned my windows and you could see faint spotting, i filled tank with pure and water was allmost pure as there was 026 water left in tank ,cleaned my other window on french doors and it was spotless ,that was 011 water so now i let it go to 006 then change resin

Rain wont be 000ppm when it hits the glass, should we clean in the rain or if rain is due on the day ? some of you guys cant see the wood for the trees. lol

No your right, thats why i get hundreds of complaints and have to work the whoke day again that i did in the rain,,,,, ::)roll ::)roll ;D

Huh?
I'm saying that rain will be above 000 so if it's ok then why can't above 000 be ok to clean with.

No it’s down to technique as well but with the best technique in the world you won’t get good results with poor water quality both are needed but you are likely to get better results with a poor cleaning approach and pure water
-
Another reason for getting spots in the warm weather is that the water has dried before its washed the contaminates away. A window cleaner in Cyprus says they have to spray the window first and cool it down before they can clean it. So you need to rinse a lot more when cleaning those sun facing windows.
And of course you also need to use pure water rather than 'thats good enough' pure water.
Correct.
The hot glass will eat your water so you need to use more.
It surprises me how many window cleaners don't get how the prevailing conditions affect the job
Two separate windows on the same house can be very different to clean.
-
Not quite on subject but im more weary of windows that have been in the blazing sun all day for when I come to clean them. As, I could be wrong and probably i am, but the metal in the frames could have already expanded due to the heat and so when I add even hotter water to the window I feel I have more chance of cracking the glass now, than in the winter months
-
Some glass is just plain pants and has ingrained marks all over it. In full sun they look diabolical. My old house had pants glass but they weren't that old.
WFP doesn't always get the best results over trad.

I clean if its raining, unless its sideways rain with gales. Thats just stupid.
If people think its ok to mess me abouy becouse it might rain, or looks like rain, or is lightly raining, i simply say....
oh good, its going to rain that means my bills wont need to be paid then due to the rain, you know i save so much on gas and electric, rent, fuel, food etc as of course its all free of charge when it might rain...
That makes them think and realize we doing this for a living, not because we feel like cleaning windows out of the kindness of our souls.

I'm not saying that you should or shouldn't clean in the rain, the point I'm making is that if rain water which is above 000 can
land on the glass without spotting then its going to be the same with the water in your tank if its above 000.
-
Aggreed to a point. The rain does bring dirt with it again, thats why they get dirty eventually. But yes the wont spot like having squeegied windows using soap.
As far im concerned, i tell my customers that i use de ionized water, that is as close to 100 % pure as i can get it. Keeping it at 000 is good practice as it backs up my claim, i dont understand why take the risks cleaning at 005 or 015 your risking your reputation and if you claim to be using pure water, thats a false claim.
It doesnt cost any more or any less to change it when it gets to 001.
-
ive just filled up for tomorrow...my water is reading 001.should i dump it down the drain eh marc? ;D
-
Yes. ;D

Do you store your water as DI Daz?

This is very Intresting since using hot water we are actually quicker on a hot day , cold water will turn to steam far quicker than hot does don’t understand the science behind it but that’s how it works for us and we do a lot of costal work lagged with salt never get spotting and don’t find we use more water on hot days we do the same jobs summer and winter and always do the same amount of work each day with very similar amounts of water
-

Do you store your water as DI Daz?
yes marc.....i filled a second DI on friday(as my single vessel was reading 004)so its now down to 001(due to having a bit of higher TDS water left in my tank from friday)....
so from tomorrow evening when i fill up again itll be 000.(it takes me 20-30 mins to purify my water DI only)
-
Hmmm ok.
So you dont DI on demand?
The tank water in the van is RO water and its pumped and deionised as its used.
