I would love to rinse on but i have no confidence.
What about the dirt on your brush, surely there is an affect on the quality?
I know you do a lot of comercial stuff Peter and i can understand you rinsing on in that situ, but would you recomend rinsing on on houses mate?
A window is a window whether it is on a commercial building. a house, a foot off the ground, or 60 foot up, they are all the same, and should be cleaned to the same standard.
When the brush is working on the glass it is the same as the window being rinsed with the pure water. Now supposing your brush is dirty before you start cleaning the window, which it isn't but lets say it is, as soon as the water starts to flow through it the brush along with the window is being cleaned. The brush bristles don't absorb or hold dirt, all they do like I said earlier is move a particle from it's fixed position, and the water will wash it away.
There is a few things that will stick to the brush one of them being spiders webs, and when they do they stay on the brush until you pull them off, they don't smear over the glass like they do with the applicator and soapy water. They don't even cause a problem if you leave them on, just pick them off after a few windows. Another thing is leaves and organic matter, and a quick flick of the bristles with your hand while the water is running, will knock any off the brush.
