Black Shower Tiles

[pxie]

Any ideas for cleaning hard water marks off black shower tiles? Normal cleaners like Viakal don't seem to work. The tiles look lovely and black and shiny when wet but as soon as they dry they have white patches all over them.

Thank you

Try a magic eraser to remove the marks and buff with glass cleaner.

try this limescale spray i use all the time for getting rid of hard water marks and also use a scourer sponge.
