The Best Ways To Safely Remove Moldy Caulk From Your Bathroom
Mold thrives in humidity, so you'll often find it growing over caulk in your bathroom. When tackling this mold, wear non-porous gloves and a mask to prevent breathing any of it in.
Bleach is commonly used to clean mold, as its main ingredient, hypochlorite, will turn into hypochlorous acid and act as a biocide when
mixed with water.
First, dilute every cup of bleach with a gallon of water. The CDC strongly advises against mixing bleach with ammonia or other common household chemicals.
Pour this mixture into a spray bottle and squirt directly over the affected surface. Let it sit for at least 10 minutes, scrub the area with a brush, and rinse
it with water.
If you're not big on using chemicals, vinegar is a wonderful alternative. White vinegar contains antifungal and antibacterial properties capable
of killing 82% of all
mold species.
Pour vinegar, with 5% acidity or higher, over the mold and let it sit for an hour. Scrub it with a brush and wipe it dry with a clean rag that you can throw out.
For tougher stains, mix 2 or 3 teaspoons of baking soda with a cup of white vinegar to make a paste. Leave this on the mold for 5 minutes before scrubbing, then rinsing with water.
To get rid of mold with ammonia, fill a spray bottle with a 1:1 ratio of ammonia and water and spritz the area. Keep it on your caulk for about 2-3 hours, then rinse with water.
For stubborn stains, soak a paper towel in your mixture and let it sit for four to five hours. Scrub the area with more of the mixture and a brush before rinsing clean.
