Looking for some help, just finished having a new bathroom fitted and spent the morning cleaning it only to have streaks still on the chrome fittings and shower screen. I also have little tiny blue marks in the bath (the size of pinheads) which weren't there when the bath was fitted. Has anyone got any great cleaning tips for me? I've always lived in rental until now and I do pride myself on having a clean bathroom but now I am very houseproud and would like it sparkling (or at least not streaky...)
