How do I get dark stains off of white tile?

I had my floor tiled a few years ago and there are black stains on the white tiles, can they come out??

Don't use a wire scouring pad if the stain is on the tile.

Don't use pour bleach, sprinkle it all around the stained area and scrub and whip the stain away.

It's possible to assume on bathroom tiles around the toilet and shower.

If it is a black grout, then your work is cut out.

If you assume the worst, keep in mind that the grout is designed to stick to the unglazed sides of the tiles.

You can use a razor blade scraper tool.You can slide the blade along the tile at an acute angle and remove the grout, like cleaning a cookie sheet with bad carbon build up.Change blades frequently for large jobs.
