First job this morning was a commercial building, and decided to WFP it for the first time. THE RESULTS WERE SHOCKING TO SAY THE LEAST. I was in direct sunlight at 7.30am. My TDS reading is at 011, which im aware is not ideal. The flow was relativly slow but I gave them a good clean and rinse.
Once dry, the windows were covered in spots and streaky all over, so got the trad gear out but even then I couldnt shift it. Something is not right. Ive spoke to the owners and said i will try and find a solution, and get the windows back to normal.
The picture below is some of the windows that ive ruined, but you cant see the spots/streaks.
Help ???

tds should be more or less OK. Check to see if frames are oxidized by running a wet finger along them and if your finger gets coloured by the frame that is the problem. Do this on the sunny side of building as this will be the most oxidized. If there are rubber seals do the same with these.
Other than that it could be that they were just very dirty and you need to use a higher flow rate and spend more time on the glass and frames.

We have some similar. They may have a coating on them and along with being in full sun it seems to leave some of them spotty. If trad gear can't shift it I would presume it is the glass coating.

Have you cleaned these windows before the traditional way?if so wot was in the bucket? is this the first time using wfp?

The frames seem good and newesh so I don`t think there is no problems with the frames and would say you need a bigger flow rate i had this a week back on a town house not cleaned to 2 years had gone over 4 times before it was fine. My pump delivers 3 litres a min and I feel it should be at least 5 litres a minute as we float the dirt off we need water on the glass to do that. Don`t panic just try to suss it out.
-
firstly I would look at your water, and try to use 000 so you can rule it out, it is not a good idea to have 11 tds when your first starting let alone know what your doing.
My guess is you didnt clean them right and the sun baked on the bits you missed.
as I say lower the tds then you cant blame the water, I have been cleaning today in the baking heat and not had any problem, but then again I no my water is perfect.

Ive just ordered new resin. Ive cleaned more houses with it today and they have been perfect. Its something to do with their glass.
The problem I have is that we couldnt shift the spots and marks etc with the trad gear so I need some other solution how to get them clean???

if it limescale then use lime scale remover, and do not do it in the sun it will be a nightmare

Someone else I spoke to said it might be something to do with limescale. Whys this?

The glass as a coating to reflect heat it is used on a lot of modern offices wait until it is not sunny , maybe even raini ng and do them again with high flow rate a least 2lt per min.

Thats the sort I was refering to. The marks have been there for years and wont go.

They aren't muppets.

They look like anodised aluminium frames, they are a pain in the rear at the best of times due to the pitted nature of the frames surface, they are always difficult to clean, let alone in hot sun.
Try to keep away from the frames and do not do any lower pane until dripping has stopped from above.

I had this last wed,wfp a shopfront after tradding for 2 months previously,results were awfull,soon went back to trad,and am sticking with it for shopfronts quite enjoy it as well
-
hard water marking or somthing like it looks like aluminium frames like leaded windows there is a residue run off when rain or wfp work
-
My guess is the marks were there before & it's nothing to do with todays wfp clean. ;)
Newbies to wfp are often paranoid over "spots", you WILL see spots & marks on some glass that you never even noticed when trad! ;)

That and the fact that they have been done trad before. Rinse rinse and rinse some more.

Just been back to the job, and the windows look mint, you cant see a spot or streak anywhere, buts thats only cos the sun isnt shining on them.
Ive soaked 4 panes of glass in white vinegar, rubbed throughlly, and then trad'd them again. Gonna call back there tomorrow when the sun is shining on them to see if its made any diffrence.
The marks were 100% not there before I started.
I licked me finger then wiped the frame and had nothing on me finger.

If there is still an issue tomorrow when you inspect, I guess they will need to be WFP's again. My suggestions are 000 TDS and a higher flow rate as has been suggested. Additionally, I suggest the following. Work along the entire top row ensuring that you scrub the horizontal frame below it. Hopefully, by the time you start on row 2, any drips/runs will have stopped from the horizontal frame. When doing row 2, perhaps stop the brush just below the seal between row 1 and row 2. While cleaning row 2, also scrub the horizontals below that - and so on. I solved a problem this way once but there's no way of knowing if it will help you.

Indeed. Leaving the frames completely may be better than my own suggestion.

Have to agree. One clean with WFP would not cause permanent spots no matter how bad your water.

two reasons first you have to have tds of 000 if you use water that is anything higher than that you might aswell clean windows with tap water second you must rinse lots and lots and lots there will be a build up of grime and dirt over time pure water will keep on drawing this out

I did all last week with 015ppm, zero spots! ;)

Thanks everyone for the replys n suggestions. Ill see what the outcome is tomorrow. To be honest i shoud of just trad'd the whole job as its great money anyway, and i knew the tds was high (ish)
i ordered 25ltrs of resin earlier so should get it Wednesday. Looks like a day on the ladder tomorrow ::)

Yeah i cleaned about another 10 houses and the results were fine... including my own.

Went back today, soaked all glass with white vinegar, cleaned again traditional way, and handed in my invoice. Spoke to both reeptionists, and the owner, and no one had a problem with the glass. I said, its because the sun isnt shining on them, its hard to see without. Left it with them to call me if any problems in the future :)
