The most important step to keep your grout clean is to apply a commercial grout sealer. There are different products on the market depending on the tile and the grout in use. Unfortunately, it takes as much effort to apply the sealer as it takes effort to clean the grout. But once you have sealed it correctly, you can be sure that your bathroom will be free of mildew and mold for a long time.

If you have cleaned your grout intensively, you should wait some hours before you apply the sealer in order to dry the grout completely. To keep the grout clean, no one should enter the room during this time. Afterwords you can apply the sealer. If you re-grout your bathroom, it is recommended to wait around 48 hours before the application of the sealer. If you are not sure about the correct time or how to use the seal, you should contact the tile manufacturer and the producer of your grout seals.

Once you have decided to apply a sealer to your grout, you should also think about sealing your tiles. In general, you can divide the available sealers into two categories. The first one contains membrane forming sealers. Those sealers resist water and many chemicals with a membrane which is almost invisible for the human eye. It is recommended mostly for floors. The other one is the class of penetrating sealers. It fills the remaining pores of the tiles and the grout and hinders water and other particles from entering. It is recommended for very wet places like baths or showers. It is recommended to renew the seal of tiles and grout every two years.

After you have sealed your tiles and grout, you should keep your bathroom clean. Remember that no seal offers an unlimited protection against water, dirt and other chemicals. A sealed grout can be destroyed easily if it is exposed to aggressive cleaning detergents for a long time. Therefore you should clean your bath regularly and store aggressive chemicals in a safe place.

Every three to six months you should clean your bathroom intensively in order to prevent infestation of mold and mildew. There are many effective cleaning detergents and utilities on the market that can help you to keep your bath clean. Since the bathroom is one of the most sensitive rooms in your house, you and your family should stick to some rules. Nobody should enter with dirty street shoes the bathroom. This is the main source of germs and bacteria which might spread easily in the bathroom. You should air the bathroom twice per day for at least 10 minutes in order to prevent infestation of mould. You should keep your house and especially your bathroom as dry as possible in order to protect the sealing of your grout as well.
