I was cleaning these smallish windows today and they have a metal frame thingee separating each pane of glass. It is quite sharp- could it damage my squeegee? I was using a small six inch squeegee. i would use the applicator and then wash four panes then use the small squeegee to wipe downwards twice then a microfibre cloth to detail and dry off any bits the squeegee hadn't taken care of, is this the right way? This was my second job and the whole house (bungalow) took me 2 hrs, i asked for £15 but she paid me £20 and wants me back, but I thought I would earn more than this, am I pricing wrong? Also the frames and sills were filthy, with spiders and their nests etc and webs, is it the case of using a 50cm by 25cm towel to clean all that? Any spiders in the Uk that bite lol?
