While porcelain tile boasts exceptional durability, there are few products and techniques you should take pains to avoid: 1  Never use a product containing ammonia or bleach (or any type of acid-based cleanser); these can alter the tile color and/or stain the grout. 2  Never use oil-based detergents or wax cleaners.
Hereâs how to clean ceramic tile that has been stained. For coffee, tea or juice stains, wash the tile surface with hot water and detergent, then blot with hydrogen peroxide.
