Just received free sample of GG3 from The WindowClean Centre (thanks Anne !) and used it yesterday on an office block whose windows are always covered in crap, insects, cobwebs etc, it was the mutts nuts! brilliant. I have always spent ages detailing, I thought that was the way it was (self taught), not any more! ok, maybe just a quick wipe round with the scrim, and wipe the cill but cut my time in half! The fairy liquid's in the bin!!!
Thanks for the info guys!
