Can you guys please explain this a bit for a newbie? Are you talking about the difference between rinsing the glass with the brush touching the glass or with the brush an inch or so off? Or is there more to it?
Nope you've hit the nail on the head, some people rinse with the brush off the glass some rinse with it on and others don't
even bother rinsing, they will all tell you that their method is the only way to do it right.
High flows, ultra pure, nuclear resin, jet shapes, genetically modified brushes, water heated to a sweet spot, plastic restoring additives the list goes on.
Windows cleaners have turned what is basically removing a small amount of dust from a pane of glass into a complicated
science that even Stephen Hawking would have trouble getting his head around.
