Sealing Grout - Cleaning a tile floor (or any other type of ceramic tile surface) usually gets down to the grout between the tiles. Grout that has not been sealed is vulnerable to spills and other stains. It is much easier to clean the actual tiles than the grout.

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.

Sealing Grout - Tile grout can be difficult to remove stains from, especially if it has never been sealed. Mold, mildew, food and beverage stains, and a host of other problems can make your grout look old and dirty way before it's time.

Start with a household solution of vinegar or baking soda before moving to more harsh commercial cleaners. Dilute vinegar with an equal amount of water. To use baking soda, mix with enough water to make a paste. Apply the homemade cleaner in small circular motions with a nylon brush. Rinse thoroughly with clean water and dry.

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.
