I recently tiled my en-suite with 60x30 black qrock porcelain tiles. We are now a few months down the line and the immediate wet area within the shower cubicle has become very stained, bordering on turning white. I always rinse the walls after use so that no soap/shampoo residue is left on face of tiles. I have tried numerous cleaning products which all look great until the tile dries out and the staining remains.
