Shower Floor

[terrya]

I have noticed over a period of time that the white grout between the mosaic tiles on the shower floor are going dark grey in a few areas. What should I put on it to make it white again.

Scouring powder and a scrubbing brush ?

Lakeland online site - mould remover, have forgotten the brand - spray on and leave - but do wear protective gloves and stand well clear. It is absolutely brilliant! It's basically mould causing the white grout to turn grey/black. Really recommend this product .... been using it for a few years now.

HG mould spray is excellent and can be bought at most hardware stores like Robert Dyas.
