ANSWER

ANSWER - Absolutely do not use muriatic acid to clean your grout, because it can etch your tile damaging the surface, and it can permanently stain the grout. 

Tile and grout need to be cleaned with a proper cleaner to make sure you don't damage the tile surface or bleach the grout. Use products manufactured for tile, which you can find on our website under Expert Answers' Resources and then listed under Cleaners and Sealers. Use a brush on an extended handle for floors or otherwise for walls and abrade the surfaces to get them clean. Make sure your tile won't be scratched by the brush. Follow cleaner manufacturer's instructions. Change your cleaning water frequently. For floors use a wet and dry vacuum to remove dirty water. Rinse walls. For tough stains use a poultice from the cleaner manufacture. Good Luck!
