For stubborn grout stains, mix a paste of baking soda and water. Apply it to the stain, let it sit overnight and then scrub with a nylon brush. Don't use a metal brush as it will scratch the tile. Let the grout air dry, then put on a silicone-based grout sealer to resist future stains and dirt.

Ceramic tile floors are a popular flooring option. They're durable, but like all floors, they need care and cleaning. Here are some smart tips on how to clean tile floors.

One of the most important things in knowing how to clean tile floors is keeping the grout clean. Dirty grout equals dingy-looking floors. Grout is porous and easily absorbs dirt, grease and other materials. Spray the grout with a commercially prepared grout cleaner. You can also use a mild bleach solution. It's a good idea to wear gloves when using these types of products. For deep stains, allow the cleaner to sit for 10 minutes. Use a toothbrush or other small scrub brush to scrub the grout.

Here's 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. For grease stains, wash with club soda and water, or a commercial floor cleaner. For ink stains, soak a cloth in diluted bleach and lay it on top of the stain. Leave the cloth until the stain is gone. Rinse thoroughly when done.
