How to Clean Mini Fridge – 7 Proven Methods for Fresh Results

Why Mini Fridges Still Need Major Cleaning

Mini fridges might be compact, but they can hide big messes. Whether it’s for your dorm room, home office, Airbnb unit, or garden bar, these smaller fridges still collect spills, crumbs, and odours just like full-sized ones.

In this guide, we share 7 proven ways how to clean mini fridge properly and safely—without damaging the cooling system or leaving behind unpleasant smells. These methods work whether your fridge is slightly used or overdue for a deep clean.

1. Unplug and Empty Everything

Always start by unplugging your mini fridge to avoid any electrical risk. Remove all food, drinks, trays, and bins.

• Discard anything expired or leaking
• Store perishable items in a cool bag temporarily
• Let the fridge defrost for 30–60 minutes if there’s ice buildup

2. Remove Shelves and Drawers

Mini fridge shelves are often removable. Take them out carefully and wash them in warm, soapy water.

Let them air dry completely before reinserting. This prevents mildew and bacteria growth.

3. How to Clean Mini Fridge Interior with Baking Soda

Mix 2 tablespoons of bicarbonate of soda with 1 litre of warm water. Dip a clean cloth or sponge and wipe down all internal walls, seals, and door compartments.

Baking soda is a gentle, natural deodoriser that won’t damage your fridge lining.

4. Target Stubborn Smells with Coffee or Lemon

Got a lingering odour that won’t budge? Try this:

• Place a bowl of dry coffee grounds or fresh lemon slices inside
• Leave overnight with the door closed
• Repeat for 2 nights if needed

5. Disinfect the Door Seal

The rubber door seal often traps food residue and mould. Use a soft toothbrush with diluted white vinegar (1:1 with water) to gently scrub the folds.

Dry it thoroughly with a clean cloth to prevent moisture build-up.

6. Clean the Exterior and Vents

Wipe down the outside of your mini fridge using warm soapy water. Avoid harsh sprays or bleach.

If there are rear or side vents, gently vacuum dust build-up to help maintain airflow and efficiency. A soft brush attachment works best.

7. Deodorise and Maintain Regularly

Once your mini fridge is spotless, maintain freshness with a small bowl of baking soda or an odour absorber like Activated Charcoal Fridge Deodorisers.

Set a reminder to wipe it down every 2 weeks and do a full clean every 2–3 months for the best results.
