whats gg3?
what sort of mix would you use?
would you then squeegee off and dry or just squeegee?
cheers
No offence mate, but have you ever cleaned a window before. If not I would practise and practise before shelling out on a trolley system.
gg3 or gg4 is a detergent designed for window cleaning, squeegee off is another detergent that some add to help the blade slide easier and help remove all residue from the glass.
If cleaning bottoms trad I wouldn't waste your pure water to do that because as soon as you start adding a cleaning solution it isn't very pure anymore and as your taking it off with your blade ordinary tap water is fine
