okay so im really miffed off today >:(
after yesterdays custy moaning about water marks left on the glass ive been checking all my windows today and ive noticed a few have these very same water marks too :o
mostly in the same place at the bottom about 6 inches from the bottom of the glass and sometimes the edge of the glass too!
im only using a trolley and im only D.I so to conserve water i have my pump setting very low but never thought this would cause those marks? how can it? its vloody pure water!!!
HELP :-[

sounds like you need to rinse more mate!is it spotting?i use a trolley and use a high flow.in this warm weather you need to use more water.scrimping on water is not gonna give you a good finish mate!
-
Have you checked your TDS after DI?
Have you checked your TDS after brush jets?
Do you clean frames and cills every clean.
Have you been rinsing enough?
Is your brush contaminated in any way?
:)

Very true! Don't be miserly with the water. It needs to have the weight in it to float the dirt to the bottom of the glass and sheet. In this weather, if it doesn't have the volume or weight to make it to the end it will leave streaks as the dirty water has run and cannot make it any further.
Spots in the middle - not enough scrubbing.

yes daz, its spotting around the bottoms and on one glass pain it was slightly around the edge too!
do you only pole 1st floor and above daz or are you 100% w.f.p?
my method of maintenence clean poling is quick little scrub on frames, then one scrub on glass quick rinse then 2 or 3 scrubs on sills
its hard to describe my working method in words but what is your poling method like? and how many ltrs of water would you use for 1st floor average 3 bed semi?
thanks mate

when i read your post i think i just had a "light bulb" moment :)
ive actually never thought about it before but...
1) the window has dirt on it
2) i scrub the dirt with brush head
3) i rinse the dirt that has now mingled with the water to become dirty water
so, if im not scrubbing and rinsing enought the dirty (and no doubt high ppm) water is gonna leave hard water marks of the glass :-[
WHOOPS
looks like i'll be getting my ladders out alot in the near future for some hard water mark removal :-[
god im stupid :'(

i always rinse brush off after a good scrub of the window making sure i rinse all the way down from the top edge.in this weather with all the dust about ive been rinsing twice on dirty windows.
my flow control is on 60 all the time.i use 5 mm extension hose and pencil jets.water is always 000.
im about 80% WFP/20% TRAD and use 250-300L ON A FULL DAY.
I very rarely get any problems apart from the odd leaky seal here and there.

thanks daz, what do you mean by leaky seal mate? as in glass rubber seal?
thanks
-
but one thing that my theory doesnt explain is why doesnt rain create hard water marks when it mixes with the dirt in the glass ???
-
yes rubber seal GB.OCCASIONALLY i get water trapped in a top rubber seal and it runs leaving a small line of spots when dry!!i think we all get it on the odd window. ;D ;D
-
Daz... oh right i know what you mean now mate ;)
so what do you think to my theory's mate?
-
one of my windows at home is very dirty it rained the other day and the rain spotted the dirt along the bottom of the glass.
so to test my theory i have just buffed the dirty water marks off with a scrim and they same off easy! so why as my PURE water stained my custys glass? it wont buff out ive tried?
im very confused about dirty water and ppm of dirty water ???
-
anyone got an explanation about dirty water tds? ;D
i know im annoying but its bugging me ::)
-
so how you remove these marks ?

so how you remove these marks ?
i havnt! they wont come off :( i think i will need to use my hard water stain remover in the end
-
You have created the dirty/hard water via the pure dissolving the muck on the window and not rinsed it off properly,allowing it to collect at the bottom. Simple as that.

You must only work about 2 hours a day then!!!!!!!!!! ::)
-
to use 300L on a full day i would have to work 7 hours on the glass to be coming home empty!i was pleasantly surprised when i realised i didnt need 500L A DAY because some of you were saying before i went wfp id run out at lunchtime with only 250L! ;D ;D ;D

There must be something seriously wrong with your pump then Dazmond!!!!! I have a 400ltr tank at the moment, but as soon as I get a bigger van I'm going to fit it with two 500ltr tanks so I can work all day without having to refill!!

i have that MDR but trie dit once a while back and it was useless

ive only seen hard water marks on 1 window that comes to mind,it was a lower window and i realized my scraper might take it off because my scraper made a rasping noise as it went over the marks.
wetting the window ,i now couldnt now see the marks to know exactly where to scrape but by carefully scraping the area until i could hear no rasping noise i knew the window was then free of them. i had the scraper at a tad steeper angle than normal,and was taking great care . i did this window as an experiment and the homeowner never knew anything about it but if it was a paying job,i most likely would try limescale remover firstly.
ive no idea how the window originally got the marks,they were there long before i came there ,probably they got there by the other theories posted on this thread ,such as many years of rain spattering off a dirty sill that had lime on it .

thanks sean, this is also the conlusion im coming to at the minute! unless anyone else as got any ideas?
but this still begs the question, so why doesnt rain water that dissolves the muck on the window stain the glass?
ive got dirty windows at my home that the rain as rinsed the dirt to the bottom of the glass but it wipes off easy!
the water marks ive created on my custys windows WONT shift :o ??? ??? ??? ??? ??? ??? ???
