4 Steps to Remove Mold From a Cooler

Use bleach for heavy mold Mix one tablespoon of bleach per quart of water. Vinegar only works for light mildew, but black spots need bleach to kill the roots.

Scrub gently with a soft sponge Avoid abrasive pads that scratch plastic. Mold loves scratches, so a soft sponge prevents future growth.

Let the solution sit for 15 minutes Apply the bleach mixture, wait, then rinse thoroughly. No bleach smell remains if you rinse well.

Dry completely before storing Wipe with a towel and leave the lid open for a day. Moisture is what caused the mold in the first place.
