How to Remove Mold From Rubber

When mold forms on rubber, it's important to kill and remove it quickly to prevent long-term damage. Because rubber is porous, the mold may penetrate the surface of the rubber. Eventually, this can cause the rubber to fall apart. Both vinegar and bleach are effective at killing mold. Bleach kills mold faster, but may discolor or weaken the rubber. Vinegar takes several hours to kill the mold, but will not damage the rubber.

Vinegar

Step 1

Protect your skin and eyes with rubber gloves and goggles.

Step 2

Fill a clean, half-gallon spray bottle with white distilled vinegar. Screw on the lid.

Step 3

Spray the mold with the vinegar, and let the vinegar saturate the mold for two to four hours.

Step 4

Rinse the rubber with water, and dry it thoroughly.

Bleach

Step 5

Protect your skin and eyes with rubber gloves and goggles.

Step 6

Mix one part bleach with four parts water in a clean, half-gallon spray bottle. Screw on the lid.

Step 7

Spray the mold with the bleach. It should begin to kill the mold instantly. Leave the bleach on the rubber for at least 15 minutes.

Step 8

Scrub the mold away with the brush.

Step 9

Rinse the rubber clean with water, and dry it thoroughly.
