.. is it best to get a double sided washer thing (Huh) to scrubb REALLY dirty green algee ridden window frames ?
Ask the punter first if they'd like you to do that as you can provide other services in addition to just cleaning the glass - £££!! Don't use those green scotchbrite pads, see if you can get some white ones instead - they don't scratch. Green algae comes off quite easily, but don't tell them that.
when you get cats sat at windows (not at the actual time of washing)... does anyone fird it hard to get rid of all the fur ?
Just give it a couple of extra goes with the applicator, or the white pad.
whats the point of windows 5in wide ?
To annoy window-cleaners, of course. What other reason could there possibly be?
