How To Get Mold Out Of Caulking

Posted on

If you smell something foul in your bathroom or kitchen, it could be mold on the caulking. A foul odor is commonly the first sign of mold as well as orange, black, or green growths.

Caulking helps form a water tight seal on sinks, tubs, and showers, but these moist environments are breeding grounds for mold. Mold left untreated can create a health issues such as allergies so you should clean it right away. Here are some tips to remove mold from caulking without using toxic substances.

Get Prepared

Some things you need for this project include:

  • utility knife
  • bucket
  • detergent
  • baking soda
  • bleach
  • spray bottle
  • plastic or drop cloth
  • several old cloths
  • old toothbrush
  • exhaust fan
  • lemon juice, apple cider vinegar, or white wine vinegar
  • caulk 

When you work with mold always wear old clothes, gloves, and a dust mask to protect yourself from the spores, and open a window to ventilate the area by opening a window. If there's no window in the room, set up an exhaust fan. Cover carpeting with plastic or a drop cloth so it won't get discolored.

Remove Surface Mold

If the mold has formed in spots, you may be able to clean it without removing the caulk.

  • Dip an old toothbrush a small amount of lemon juice, apple cider, or wine vinegar, and let it set several minutes.
  • Squirt the area with water, and wipe with a cloth.
  • If this doesn't help, mix enough white wine vinegar in a spray bottle with baking soda until a paste forms. Moisten the molded area, and leave it on for several minutes.
  • Mix a small amount of bleach with water, spray the mixture on the mold, and let the area dry before wiping it off.

Remove Stubborn Mold

If the mold has spread or keeps coming back, you will have to remove the old caulk to clean mold.

  • Scrape the old caulk away with the utility knife, disinfect the area with bleach and water, and let the area dry before applying new caulk.
  • Mix 1/2 gallon of warm water with a ½ tablespoon of detergent ,and ½ cup of bleach in a bucket.
  • Soak the molded area wit the mixture using a sponge or cloth, and let set for about ten minutes.
  • Remove excess mold with the old toothbrush.
  • Wash the caulk with warm water, and dry with a cloth.

After you have complete the mold removal process, reapply the caulk. To prevent future mold, ventilate the room, and keep the area free of moisture. If you think the mold is too much for you to handle yourself or it keeps coming back, contact a mold remediation company.
