How to Clean Black Mold on Refrigerator Gasket in Minutes

A clean refrigerator is essential for food safety—but over time, the rubber gasket (the seal around the door) can develop black mold or mildew. Not only does this look unpleasant, it can also affect the freshness of your food and create an unhealthy environment. The good news? You can remove black mold quickly and safely with simple household ingredients.

Why Mold Grows on Refrigerator Gaskets

• The gasket is moist and cool, perfect for mold growth.

• Food spills, condensation, and trapped crumbs provide nutrients for mold.

• If left untreated, mold can spread, cause odors, and even compromise the gasket’s seal.

Step-by-Step Cleaning Guide

1. Prepare the Cleaning Solution

• Mix equal parts white vinegar and warm water in a spray bottle.

• For stubborn mold, sprinkle baking soda on the gasket and spray with vinegar.

• Alternatively, use hydrogen peroxide in a spray bottle as a strong, natural disinfectant.

2. Spray the Gasket

Spray the solution directly onto the black mold on the gasket. Make sure to cover all folds and crevices, as mold often hides in small spaces.

3. Let It Sit

Allow the solution to sit for 5–10 minutes. This gives the vinegar or hydrogen peroxide time to kill mold spores and loosen buildup.

4. Scrub the Mold

Use a soft cloth, sponge, or old toothbrush to scrub the gasket gently. Focus on corners and folds, where mold tends to accumulate.

5. Wipe Clean

After scrubbing, wipe the gasket thoroughly with a clean, damp cloth to remove any residue.

6. Dry Completely

Use a dry cloth or paper towel to dry the gasket completely. Mold thrives in moisture, so keeping the gasket dry helps prevent regrowth.
