Things You'll Need
DuraCeramic tile is designed to resemble ceramic tile, only with the easy-cleaning and heavy-duty wear features of laminate tile. And, just like ceramic tiles, DuraCeramic tiles are held in place by grout. No matter what you do to prevent it from happening, grout gets dirty. Whether mud and dirt get tracked in by pets, or the dirt accumulates from everyday use, it must be cleaned. Thankfully, you don't have to use fancy grout cleaning solutions, because the simple, homemade ones work just as well.
Combine 2 tablespoons oxygenated bleach with 3 cups of hot water in a bowl, or follow the package instructions.
Soak the rag in the bleach solution, wring it out and then rub the solution onto the floor applying it directly to the grout. Re-soak the rag as needed. Repeat until all of the floor grout has been covered.
Let it sit for 15 minutes in order to fully loosen the dirt and mildew that are caked onto the grout.
Scrub the grout with an old toothbrush until all of the dirt is gone. Re-soak the grout as needed to remove any stubborn stains.
Wash the floor with soapy water to remove any excess dirt and bleach. Dry the floor with a soft towel.
