Squeegee the grout after you shower. Try to get in the habit of using a squeegee to remove water from the surface of the tiles and the grout in your bathroom after you shower. Drying the shower doors and the tiles in the shower helps to prevent a buildup of grime or mineral deposits in your grout. You can attach a squeegee to the inside of your shower with a suction cup so it is right there at the end of your shower. Encourage others in your household to squeegee off the shower once they are done to keep the grout dry and clean.
Use a sealing product on the grout. You can also maintain the grout so it looks its best by using a sealing product on it. Seal the grout once or twice a year so it remains water repellent. This will ensure the grout stays clean and grime-free. You can find sealing products for grout at your local hardware store or online.
Replace the grout if it becomes damaged. If you notice the grout in your bathroom or kitchen is shrivelled, full of mildew, or damaged in any way, try to get it replaced as soon as possible. Replacing the grout will ensure it does not get worse or you do not experience other home repair issues as a result of damaged grout. You may try cleaning the grout before you consider replacing it. If it does not respond well to cleaning, it may be time to switch it out for new grout.
This may also lead to a stain on the tile or the grout. Use a wet mop or a wet cloth to rinse off the cleaner. You should then dry the grout and the tiles well once the cleaner has been rinsed. Use a towel or soft cloth to do this. Do not use cloth that will scratch the surface of the tile or the grout.
Try a salty vinegar mix. Combine ¼ cup (21 grams) salt, ¼ cup (21 grams) baking soda, and ¼ cup vinegar (60 milliliters) in a tall cup or small bowl. Let the solution sit for 20 minutes, then use a small spoon to apply the mixture to the grout. Using a toothbrush or scouring pad, scrub the grout until clean. Once you’re finished, mop the grout or use a damp cloth to wipe the grime away.
