Cleaning Wax From Ceramic Tile

Acid works, be careful.

Peroxide for the dirty cracks.

Having done a bit of household remodeling, I recommend regrouting the area entirely. Hardware stores sell a tool for removing grout between tiles for just a few dollars and regrouting is very simple, you just wipe it on and wait, then polish the tile when dry. If you don't mind skipping a shower for one day, it's a worthwhile project - and you won't have to use quite so much elbow grease or chemicals!

Hello- I would try heating the wax with a hair dryer and wiping it off. As
for the grout, I think I have heard people say that vinegar works; bleach
also should work. - Karen

Have you tried ammonia? I know it smells to high heaven, but I have always had good luck with it.
Hope this helps.
