Lifting the brush off is kinda bad practice, you can't lift the brush head off at 45ft you'll do yourself an injury! Why do it on the first floor but not on higher floors? Are you doing a worse job higher up as your not lifting?  it doesn't make sense. Keep the brush on the glass. A good side to side motion as your bringing the brush down will suffice as thats when you are really washing away the dirt.

A good way to see how dirt is cleaned from windows is to clean some white cladding. you can really see how to get dirt off effectively, agaitate it first then rinse away. lifting the brush off causes spray which can hit recesses and cause the dirt to run onto the window from somewhere else.

good point

One question I have Is for those that rinse on the glass do you also clean the sills? Reason I ask is because  I have done both on  bottom windows and had all sorts of debris not rinsed away on the glass, if thats happening on the bottoms where I can see, whats going on upstairs?   

[Ian_Giles]

Definately.

I had a few customers point out brush marks.
That's from not rinsing away from the glass.

actually Rog, if there are brush marks left behind it is because you haven't been thorough enough scrubbing the glass.
You most often get this happen on panes that are pretty grimy, you think you've done it properly, and you can rinse all you like, but those brush marks will remain.

The trouble is that you can only know for sure if you've done it properly once the glass has dried!

With experience you can tell the windows that need a very, very thorough scrubbing.

I almost always rinse on the glass, the process of rinsing is continuous anyway.

There are times when I'll lift off the glass, again, it comes down to experience and instinct.
But my aim is NOT to lift off, I only do so if I have to.

I want do save time and do a good job, normally both aims not possible at the same time but if you reckon it is I'll give it a go.

chris @c.m.s had a good question can you wipe the sills and rinse on the glass?

Also how do you rinse on the glass?  Do you clean the window twice? Or clean it once and then run the brush along the top?

What I see a lot is people using too much water, still cleaning when the window will be clean.  Try experimenting on bottom windows by cleaning two identical windows using less water and time on one, then going back and checking the results.

chris @c.m.s had a good question can you wipe the sills and rinse on the glass?

I don't really understand this question.

Simon.

Running the brush along the top after brushing is only effective on sheeting glass.  If you use this technique on beading glass you are just wasting water as most of the glass is not being touched by the water.

Think of it this way, on a sheeting pane with a side to side movement of the brush along the top of the glass will allow the water to flow down the glass like a big slow flowing river from one end of the glass to the other.  On a beading pane of glass with the same brush movement along the top, will lead to a few different fast flowing rivers and the water wouldn't touch the glass in between the rivers.

I don't really understand this question.

I can't speak for Chris but when I brush sills, debris can accumulate in the brush head.  I suppose there could be a risk of depositing it on the glass if rinsing with brush on the glass.

[Peter Fogwill]

If you were cleaning the sills you would do so after you had cleaned the glass.  Anything picked up from the sills or anywhere else for that matter has to be dealt with, and I don't think lifting the brush off the glass is going to deal with it any better than having the brush on the glass.  The brush will have to go back on some glass sometime.

I also would rather guarantee a good job 100% of the time as well, but this is done with technique, the proper amount of water, and the proper equipment, and not whether you lift the brush off the glass or not to do a finale rinse.

Absolutely!

Get the correct amount of flow of water and just lightly bring the brush down the glass.

and I use a backpack and never have a problem! but I do use a lot of water to make sure

In your email you said the brush you use is less dence allowing the dirt to pass through the bristles and down off the glass.

I use the superlight. Would that brush be ok to rinse on the glass?

[Chris Cottrell]

I know I said I rinse with the brush off the glass but thinking of the supalite brush comment I do rinse brush on when working at 45' and never had any problems ( this I know because at that height on a job in particular I do inside aswell )

I am not sure which brush you have, but most brushes are OK to rinse on the glass.

John, just so as you know, and before the backpack users start to have a go, I am not saying you can't get a good finish with a backpack, what I am saying is you have to spend more time on the glass to get it.  This is due to the amount of water flowing from the brush even on full power.

That superlite brush your talking about is awful on really dirty window`s,i used to think that it was brush marks also but it`s quiet simply the brush dosen`t have enough bristles to remove dirt from really dirty window`s unless your prepared to scrub and scrub and scrub oh and scrub again,i have a small made to order mono brush for my superlite pole that cleans the dirtiest window`s you`ll ever come across.I know everyone likes different brushes but everytime i used to have problems it was when i was using that brush.

[jikwan]

if you hav a fairly narrow window twist pole sligtly to the right (5%contact) 95 off the glass saves you manhandling it off the glass   opposite on the other side
same on a big sheet of glass if you like

[jikwan]

another thing and i think its critical
some glass doesnt "sheet" seems like water doesnt touch
that part-runs over it     check it when its dry   spots!
thats the time for brush on glass  but slowly down along that patch   hell thats cmplicated!!!!
i feel really bad when customers point out the spots

[poles apart]

I always rinse with the brush on the glass. You're just wasting time and water if you don't. Mind you, it depends what brushes you use. I use Ionics but I've heard Tucker's are good as well, as for Vikan the best place is the bin

I use both on and off the glass methods, both work fine.
I still can't understand why brush manufacturers site the jets in the middle of the brush.
I jet my own brushes, and put the jets in one row of bristles down from the top. The top row of bristles stop the water from going over the top of the brush and into the vents.
When I rinse with the brush on, there is far less chance of any dirt being left, there is only one row of bristles that could possibly contaminate the glass, all the rest are below the jets. Does this make sense to you. Dai
