Probably a massive newbie question, but how long do rubbers last?
As stated I only clean windows after pressure washing, so although I rinse windows with PW first they still have a lot of grit and fine muck on. I imagine this takes its toll on rubbers, its pretty much like a first clean everytime.
My blades streaking a bit so gonna turn it around.. Its lasted about 6-8 hours on the glass time, does that sound about right?
