Grout Stain - Cleaning ceramic tile floors is not very difficult. For most jobs a simple damp mop will do the trick. However, the grout is another matter. It can be very difficult to remove stains from grout that has not been sealed properly. It's also difficult to clean the grout using regular sponge and cloth mops because the tiles are usually higher that the grout.

If your grout is fairly dirty, you’ll need a stronger solution than you use on the tiles. Lysol and similar cleaners can be used almost full strength for thorough cleaning of the grout. Remember that when you use such strong solutions, you will need to go over it again with plain water. And don't let the solution sit on the grout too long. It could be absorbed and cause permanent discoloration.

The best long term solution to keeping grout clean is to seal it. This will help prevent spills from being absorbed into the grout, and cleanup is much easier.

You can purchase grout sealer online or at your local home center. There are quite a few types available, so be sure to read the labels before purchase. Silicone based sealer is applied to the grout only. It provides a long life and is fairly easy to clean. There are also finisher/sealer types that are applied to the entire floor. There are different types that will enhance and highlight both the tiles and the grout, or you can get a clear finish.

Grout Stain - Tile grout gets dirty in different ways, and the type of stain usually depends on location. In the bathroom, it's mold or mildew. Kitchen tile grout catches spills from food and beverages. Floor grout gets dirty from foot and pet traffic.

To clean the grout, first use the least acidic cleaning solution. If unsuccessful, move up to the harsher chemical cleaners. In any case, be sure to protect your hands and eyes.

Simple household items like vinegar or baking soda may just do the trick. Use vinegar diluted with an equal amount of water, or make a paste of baking soda and water to clean the grout with. Spray or dab the homemade cleaner onto a length of grout and scrub with a brush. Scrubbing in small circles rather than straight up and down will remove more debris. Rinse well with water and dry with a sponge or paper towels. After the grout dries, take a look and see if the stains have been removed successfully.

If your grout is still stained, the next thing to try would be commercial tile and grout cleaners. These are available where home cleaning products are sold. Start with a mild cleaner instead of jumping right to a harsh one. To get the best result from a commercial cleaner, spray it on and let it sit for a few minutes before scrubbing. Follow the directions on the label to clean effectively and prevent discoloration.
