How to Whiten Caulk Around Bathroom Tiles

Because the bathroom is subjected to water and steam from daily baths and showers, it is hard to keep caulk in the bathroom looking good. White caulk around bathroom tiles can easily develop mold and mildew. The caulk can even turn yellow and look unsightly. If cleaning the caulk with a powerful household cleaner fails, you will need to buy a special whitening product.

  1. Open the windows and doors in the bathroom to ventilate the area. You may also want to turn on the exhaust fan to help clear odors. Put on a pair of rubber gloves and safety goggles.

  2. In a bucket, mix together 1/4 cup of bleach and 1 gallon of water. Dip an old, medium-bristled toothbrush into the solution. Scrub the caulk around the bathroom tiles to whiten it.

  3. Rinse the caulk well with clean water to remove the bleach and dirt.

  4. If the bleach solution did not clean the caulk, buy whitening grout cleaner and sealer. Follow the manufacturer's directions to achieve the best results.

  5. Roll the whitener onto the caulk, making sure to cover all of it. Allow this product to dry for 24 hours.

  6. Apply the grout sealer to the whitened caulk and work it in with a sponge. The caulk around the bathroom tiles should now be whitened and sealed.

Warning

  • Be careful when using bleach; do not splash it on your skin or clothing.
