My Nana Taught Me This Trick to Clean Black Mold on Refrigerator Gaskets in Just Minutes

 

Your refrigerator is one of the most essential appliances in the house — but over time, grime, food stains, and even black mold can build up in one of the most overlooked areas: the rubber door gasket. If left uncleaned, this area can become a breeding ground for bacteria and mold, which may affect the hygiene of your entire fridge.

Thankfully, my Nana showed me an easy, effective, and safe way to clean the gasket — without damaging or deforming it. Here’s how you can do it at home in just minutes.

Method 1: Clean with Salt, Baking Soda, and Vinegar

It Works:

Salt disinfects, baking soda scrubs away grime, and vinegar helps break down mold and grease.

What You’ll Need:

1 tablespoon of salt

1 tablespoon of baking soda

A splash of white vinegar

Optional: A little white wine (for added shine and disinfection)

A cloth, chopstick, and bowl

Steps:

In a bowl, combine salt, baking soda, vinegar, and a little white wine. Stir until dissolved.

Soak a cloth in the mixture until it’s saturated.

Wrap the cloth around a chopstick — this gives you a narrow tool that can reach into the gasket’s folds and corners.

Carefully insert the chopstick into the gasket slots and scrub away dirt, mold, and grime.

Wipe dry with a clean cloth.

Method 2: Disinfect with Rubbing Alcohol or White WineMethod 2: Disinfect with Rubbing Alcohol or White Wine

Why It Works:

Rubbing alcohol and white wine both disinfect, clean, and evaporate quickly, making them ideal for rubber surfaces.

What You’ll Need:

Equal parts rubbing alcohol and white wine (or just alcohol)

Gauze or thin cloth

A plastic card (like an old gift or credit card)

Steps:

Mix rubbing alcohol and wine in a 1:1 ratio in a bowl.

Soak the gauze inthe solution and wring out the excess liquid.

Wrap the gauze around the plastic card.

Gently slide the card through the gasket folds to clean deep inside.

Let the area air dry — no rinsing necessary.Extra Tips:

Clean the gasket once a month to prevent mold buildup.

Always dry thoroughly after cleaning to prevent moisture from causing more mold.

If the gasket is already cracked or brittle, consider replacing it for optimal performance.

Conclusion: A Mold-Free Fridge in Minutes

Thanks to this easy trick from my Nana, keeping your fridge gasket clean and mold-free doesn’t require expensive cleaners or alot of elbow grease. Just a few pantry staples and five minutes of your time can restore that fresh, clean look — and help keep your food and fridge safer and more hygienic.

Try it once and you’ll never go back to ignoring that rubber seal again!
