Our landlord is just installing a new bathroom for us. When we moved in, our old bathroom was already quite discoloured on the tiles and grout, and then I could never shift the black stuff around the bath seal. It looked pretty unsightly and I was wondering if any one please has any tips for keeping the tiles and grout looking white? I think that I might get a squeegee to use after every bath/shower, and should I spray the tiles with white vinegar? Any tips would be greatly appreciated. Thanks. :)
