Hi
One of my tips would be to save money on the shine stuff for the shower screens is to spray and bathroom cleaner on the cloth rub is all over the screen with a clean cloth wipe off and buff up with a old tea towel or something like they come up like new and you dont leave any water marks either.
With my cleaning contract for the offices we do I get the cleaners to do everything above shoulder height on the first night, the second night they do all window sills and ledges, third night all skirting boards and bottoms of chairs etc and the other nights they just clean desk and hoover this way everything is covered in a week, seems to work for my company.
Its interesting to hear how other people spot dirt and makes interesting reading.
Thanks
Julia
