| Asked by peter green from liverpool: |
our walk-in shower(3 years old) has white limestone tiles on the floor and walls. at the very bottom of the walls we have some occasional small black stains. we probablt should have re-sealed by now - and we will when we gat the problem sorted. we have tried jif, bleach, vinegar - but cannot get any result - suggestions please. |

Hi Peter,
If you have Mould then you wont get this out unless you drill it out and fill it with a waterproof cement based grout, Limestone is not the best of Stones to put in a wet enviromnet, it needs regular sealing with say Tile Doctor colour grow to make sure nothing gets into the Stone, like Mould, Limescale etc.
