I have used up to 20 you should be fine but just incase I would avoid the realy fussy customers as sometimes it will spot but only if its really hot and a bit windy but 99%of time its fine for me

wash your car and van with it and your own windows and see if it leaves spots...this sunny weather is forecast to last all next week and it shows up every little mark on the windows.....it might be fine but you dont know what that 14tds consists of as it varies across the country depending on your water supply......how much does a full tank of water cost you?a lot less than your reputation thats for sure.....

I have been using wfp for nearly 25 years now and never went over 002 ,then at some point i forgot to check it i was going through a bad illness at time so mind was all over place and the day i checked it ,it was showing 020 i panicked like hell so went round alot of customers i had cleaned which was the realy funny ones and all windows were fine so now i dont change resin as often now normally leave it till it gets around 010 or maybe higher in winter months

I would never use 14 TDS
Even if you think you could get away with it.
Empty your tank and start again.

At 014 your hardly gonna get alot of complaints even if any customers say anything it will be a low percentage of them and most of time they will just tell you oh by the way the windows wasn't the best last time hardly gonna sack you for a one time clean where there might be a few spot 🙄

That’s why I check first thing in the morning them when I finished for the day

cloudy dull weather would be ok,     Sunny weather drying on the glass may leave light spotting.     Any complaints  just apologise  say there must be some dust in the air from china .and give them a half price clean  or  tell them to get a life and stop being a moanie Minnie,  haha

No  you must try on your own  windows and if it dries OK  good to go.

I used 025 for a couple of years when my resin run out with no problems at all.  You could probably use a lot higher in all honesty, people get too hung up on a number, there is not magical number where you suddenly get spotting. The higher the TDS the more chances there are of spotting but no one has found that number out. Carry on you will be fine, it will save you a lot in unneeded resin.

Water in my tank never goes about 4 anyway usually and it goes through a resin bottle in the van,it last ages you’d think it would last a long long time at 000 it does last months but you’d think it would last longer.
I suppose it just being in a resin bottle will degrade it somewhat over time,another debate but if you use PPB you have to calculate usage after normal resin or you won’t know roughly when to change the PPB resin.

How is it unprofessional, is there a code of practice that says you have to use resin, or only use water up to a certain PPM.

The customer has no idea what the TDS of the water is, or wether we use resin, as long as the windows are clean and you the customer is happy how much more professional Can you get?

Surly if you want to be the ultimate professional you should have a brand new van every six months, and have an new ionics parts per billion system fitted so the water is even more!

It’s not about being tight it’s about not wasting money when something isn’t needed!

Do you shop around for the cheapest insurance, do you try and buy fuel from the cheapest garage, do you try and get the best deal on a new phone contract?  Why spend £80 on a bag or resin when you can save the £80 and still have the same end result!?

Why should we always have 000 water, where does it say you should only clean windows with 000 water, it’s just something that has been spouted about on forums for years and people get brainwashed into believing it, if you have never tried higher TDS then you cannot tell other people what they should do as you are advising people without having the necessary experience.

There is no right or wrong if you are happy with the way you do things, give advise, but do not belittle people because they do not conform to your way of thinking.

Ime not intrested in getting into some slagging match but you are deluding yourself if you think you are going to clean people’s windows and get good results with a TDS of 14-20 years ago I accidentally cleaned   some customers windows with a TDS of 005 not realising it until I had several complaints I then checked the TDS and realised why they had complained, you might get away with it with some customers but low sunlight and it will stand out like a soar  thumb .

Yes I’m sure my customers come on here to see what I post!

Well all I can say is haven’t used resin for 6/7 years, my ro kicks out at 008 at the moment and I will happily let it go to 025. I’ve been cleaning for 16 years and have a successful business, I also have not had anyone complain about spotting in that time, I have had complaints when I’ve missed bee poo or pollen deposits.

I do regular inside work and get to check my work and can honestly say at 025 you do not get spotting.

Sorry but you are wrong the industry standard is to use water with a TDS of 000 or as close to it as possible all the major wfp manufacturers  recommend this figure , it’s not something plucked out of the sky the closer to 000 the quicker it will clean and the better the results you will get , that’s a scientific fact , my car will run on cooking oil but will it perform and run nicely on it ?? No way , use a good quality diesel and the mpg and running is much better it’s exactly  the same with water TDS

I think we will have to agree to disagree , no way will a TDS of 25 not  leave spotting  , if that were the case why would water purification companies sell resin or recommend its use ? Any way I cannot be bothered to waste any more time on this subject

Post by: Lee GLS on April 19, 2020, 08:45:30 pm
Why would suppliers say we should use 000 oh I don’t know, maybe because they sell resin! If they said you can clean with 15,20,25, then they would loose out on sales of resin and RO filters. There is no regulation, there is no scientific proof it’s only down to trial an error.

As for increased MPG with high quality fuels, then you have been brainwashed by internet talk about it, along with supermarket fuel doesn’t have the additives. It’s all hearsay.

I have over 100k miles logged on a fuel app on all my vehicles, I’ve tried all sorts of fuel addictive, all makes and supposed qualities of fuel and it makes no difference, the only time you need high octane fuel is if your car has been designed or mapped to run on it.

I have been in this job well over 20  years and yes we do have very fussy customers , but that’s not a problem they are paying a premium for top quality work and that’s what we give them . There will always be different opinions as what’s acceptable amongst us and the customers , I don’t care what others do it doesn’t affect my buisness but you cannot successfully clean  windows with that sort of reading and get good results , if you are cleaning windows on some grotty council estate maybe you will get away with a bit but when working on 2-20 million pound properties no way will you , we pick up loads of work from other cleaners all the time due to the things mentioned in this thread , the information given out on hear is very misleading for ones starting out you should be using 000 TDS , if using higher levels is ok why do we need TDS meters , just fill your tank from the Tap and use that , what level is acceptable and at what point isn’t it acceptable?... I have had spotting at 005 and we never get call backs there is no way we could use 014-020 and get good results .

Ime not saying the customer cheats the water with a TDS meter ime saying we should , provided the level is 000 there shouldn’t ever be any issues with spotting the only time I have had complaints was when I had a reading of 005 and hadn’t checked the TDS  for a few days that was my fault , so now I check every van every couple of days but know that usually I can get around 12 months out of the resin before it will need changing but as that time approaches I keep a close eye on it and as soon as it goes 001 or more it’s changed , that way I know we won’t have any problems, again this is depending on technique with the cleaning as well ,

Bottom line, you don't know what you're taking about, the window cleaning magazine did an nationwide experiment a few years back, in some parts of the country it could actually go to 80ppm before causing a problem, 40ppm was the most common, the high calcium areas where the worst but even they could get away with 10ppm, there's nothing wrong in keeping your water a 000ppm but its certainly not a must do.

What I would do  if I had a van tank full of 14 is take my my d. I in the van (with fresh resin) and purify it on demand.

Either that or dump it, I wouldn't use 14 I wouldnt even use 4.

Anything over 2 and I would be changing it.

It depends on what's in your water and also the weather. Hot and direct sunlight has a big effect.

But I think its bad advice and bad practice to use anything other than 0. What's the point of risking it, just use the lowest you can then you can relax knowing there's nothing more you can do.  If you use 0 it kills the debate can I use 2, can I use 10 etc. Maybe or maybe not just use zero and problem solved.

Even using 000 can still get dotty if someone in area is doing building works ,i had a full street cancel because they said i wasnt using pure water until i took a bottle of my filtered water to them and prooved it was pure ,i explained there was a big new housing estate over rd being built which was causing the dotting never had a problem since just made sure i cleaned them on a calm day

It’s to make them feel better and justify to themselves why they waste money on changing resin, and it also makes them feel superior and more professional to those that choose to use a high TDS, when in reality we are all the same, none of us are ‘professionals’ when it boils down to it we are just humble cleaners that can earn a decent living doing a very simple job that anyone could do.

Thanks for the message swanson but if you don't mind Ill let my customers judge if I'm running my business correctly or not,
nothing wrong with keeping your water at 000ppm but will repeat if you think you cant use water above that then you don't know what you're talking about.

Others don’t.
To be honest with you all and in the grand scheme of things it’s a pretty naf subject to argue about.
