Do you rinse less when the glass sheets? When beads form on the glass I rinse from side to side working my way down the pane. Is this neccessary when the glass is sheeting? Or can you just rinse from the top. Dai

Stick to one method for all windows, this way your speed will increase along with your profit!

Im always unsure what they mean by sheeting

what is sheeting?

Hello Dai,

One of the more experienced wfp cleaners on this forum advised me to rinse every window iresective of it sheeting.

They also advised me to rinse from side-to-side whilst going down the window as your already doing.

Have found its works well.

Regards,

Sarill

Chris, Sheeting is when the water forms a single film on the glass and runs down from the top of the pane right across the glass in an even body. Beading is when globules of water form in the area you have just brushed and remain on the glass after you have rinsed.
Thanks guys I thought I may have been able to get away with less on sheeting glass.  Glad I asked Dai.

Does anyone know why some glass sheets and some glass beads when rinsed with wfp?

Also, does it make any difference to the finish?

Cheers

Iv allways noticed that if you clean a window above a conservtory there is a good chance it will sheet I think its because there less chance its been cleaned b4 with detergent.
I think think it must be the detergent from previous cleans that make the windows bead.

Tosh answered this for me a few weeks back, apparantly there are two different manufacturing processes - so ask him, he knows.

Hi kingfisher

I think think it must be the detergent from previous cleans that make the windows bead.

There may be something in that statement.

Sometimes with traditional method the detergent goes into beading so maybe it's what the owners may have cleaned the glass with at some point also?

I have noticed that some windows sheet down the middle and beads close to the edge on one side . sometimes the weather can miss part of a window because of the protection of the reveal .
and the beading on the edges could be soap residue reppelling the water .as that is where you normally wipe with your scrim.and there is a build up of residue and silicones.

p.s.does that make sense ,,it is late

Apparently there are 2 types of glass, one is hydrophobic which means that the glass does not like water to form on it, this is the type which will likely bead and leave spots.  The other is hydrophillic which welcomes the water to it and will sheet every time.

Now I have found that when I come across glass which is difficult to get the sheeting effect, I really scrub the glass with the brush then rinse and scrub again, if you do this a couple of times you will find that the glass starts to sheet, and spots become a thing of the past.

[Moderator David@stives]

I have seen glass that seems to have a bit of both.so i dont think it is always the glass itself .it must be something else .

[rosskesava]

Glass is made by floating the liquid glass on a tray of molten tin. The liquid glass being lighter than than liquid tin then floats.

The glass cools and goes solid before the tin does.

So I don't think it can anything to do with the manufacturing process and the ingredients for glass are always the same - basically soda ash and silicon (sand).

Maybe I'm wrong.

I think it's a mixture of all things posted.

Cheers

I don't know if it is a residue thing, some of the windows over conservatories were cleaned with soap before the conservatories were built. I was wondering if the accumilation of dirt was acting as an abrasive scouring powder. They do sheet well though don't they?
Some panes in a 4 pane window will sheet and some bead. This is on houses built in the last 10 years with UPVC frames. surely the same glass was used for the whole window. I have cleaned these windows since the houses were built so there is no question of windowlean or any thing else being used on the upstairs windows. I have done them every month from new. It's a complete mystery to me, but there must be a scientific reason why some sheet and some bead.
Do beaders ever become sheeters or vice versa? I have noticed that well mentained Wooden frames seem to sheet better than UPVC.
It's bugging me, there must be a logical reason. Dai

Dear Graham
Sadly, I have known from the start you are underestimated.  I have only done one day of wfp.   
One of the most important things, if not the most important things I have learned in one day is .................................................
RINSE
RINSE
RINSE
There is still lots of water available...
Until they cut it off.......
RINSE
It ain't so hard to learn.. Surely.
So, I got soaked....!
But the windows on the building, worth 5mill, were clean!!
You think I joke?
Whatever!

I agree with Dave.

I have never used any detergent on my own windows but noticed on some of my customers cleans i had this problem.
 
Since i seemed to have the hang of this wfp i started to clean one of my windows at the back of my house with a detergent as an experiment.
Before i did this the window was sheeting really nice but after it was beading. I only started using detergent on it in the last 3 weeks i think (every other day i cleaned it) so after a long time using detergent there must be alot of residue build up to get through.

I found that you just have to keep brushing and brushing and plenty of rinsing and it will eventually start to sheet again.

I tried it on a customers house today as the middle of the glass was sheeting but the sides were beading. It took awhile but got it to sheet in the end. It wasn't  perfect but i'm sure next clean it will be better.
