How do you clean mini fridges?

You clean a mini fridge by unplugging it and emptying it, then wiping out the inside with a gentle cleaning solution, cleaning the shelves and door seal, drying it and letting it air before plugging it back in. First unplug the fridge (for safety and to let it warm so any frost melts) and take everything out, removing the shelves and bins. If there is ice built up, let it defrost. Then wipe the interior, walls, floor, roof and door, with a mild solution of baking soda and warm water (about a tablespoon of baking soda per liter/quart), or mild soapy water, which cleans and deodorizes without harsh chemicals, and wash the removable shelves and bins separately. Clean the rubber door seal (gasket) and wipe the exterior, and vacuum or dust the rear coils if accessible. Finally dry everything, leave the door open to air out, then plug it back in and let it cool before restocking. Our Best Mini Fridges compares five of them.

Unplug, empty and defrost

Start by unplugging the mini fridge, which is both safer for cleaning and lets the interior warm up so any frost or ice melts. Take out all the food and drinks, and remove the shelves, racks and any door bins or drawers so you can clean them separately and reach the whole interior. Emptying it fully lets you clean every surface properly.

If the fridge (or its small freezer compartment) has ice or frost built up, let it defrost before cleaning, with the door open and a towel to catch the melting water (and a tray if needed), never chipping at ice with a knife or sharp tool, which can damage the fridge. Defrosting may take a little while, so plan for it. Unplugging and emptying also means you are not cleaning around food or cold, wet surfaces. So the first stage, unplug, empty, remove shelves and defrost if needed, prepares the fridge so you can clean it thoroughly and safely, and is the sensible way to begin, especially as mini fridges are small and quick to empty.

Clean the interior and parts

With the fridge empty, clean the interior using a gentle solution rather than harsh chemicals (which can leave smells in a food space). A mix of baking soda and warm water (roughly a tablespoon per liter/quart) is ideal, it cleans, lifts residue and deodorizes, or you can use mild soapy water; wipe down all the interior surfaces, the walls, floor, ceiling and the inside of the door, with a cloth or sponge, removing spills, sticky spots and stains. For stuck-on spots, let the solution sit a moment to soften them, then wipe. Avoid abrasive scourers that could scratch the plastic lining.

Wash the removable shelves, racks and bins separately in warm soapy water (let glass or cold parts come to room temperature first so they do not crack), rinse and dry them. Rinse the interior by wiping with a clean, damp cloth to remove any baking soda or soap residue, then dry it. For odors, baking soda is the key, both in the cleaning and by leaving an open tub of baking soda in the fridge afterward to keep it fresh. So cleaning the interior and the shelves with a mild baking-soda or soapy solution, then wiping clean and drying, removes spills, grime and smells and is the heart of cleaning a mini fridge.

Door seal, exterior and coils

Do not forget the door seal (gasket), the rubber strip around the door that seals the fridge, because food, spills and grime collect in its folds and it affects how well the door seals. Wipe the seal with the mild soapy or baking-soda solution, getting into the folds (a cotton bud or soft brush helps), then wipe clean and dry it, keeping it clean helps it seal properly and last. Check the seal is intact and not torn.

Clean the exterior too: wipe the outside, the door, top and sides, with a damp cloth and mild cleaner, and clean the handle. If the fridge has accessible condenser coils at the back (some mini fridges do), gently vacuum or dust them with the fridge unplugged, since dusty coils make the fridge work harder, though many compact fridges have hidden or wall coils, so only clean what is accessible and do not force anything. Wipe the drip tray or drainage area if there is one. So cleaning the seal, exterior and (if accessible) coils, along with the interior, covers the whole fridge and helps it run efficiently and seal well, which is worth doing while you have it emptied.

Dry, air and restart

After cleaning, dry everything thoroughly, wipe the interior and shelves dry, because leftover moisture can cause smells, mold or frost when the fridge runs again. Reassemble the shelves and bins (make sure they and the interior are dry). Then, ideally, leave the fridge door open for a little while to let it air out completely and any cleaning smell dissipate, which also helps it dry fully.

Finally, plug the fridge back in and let it cool down to temperature before putting food and drinks back in (restocking it while still warm makes it work hard and the food could warm), so give it time to reach cold again. Place an open tub of baking soda inside to absorb odors going forward. To keep a mini fridge clean with less effort, wipe up spills when they happen, do a quick wipe-out regularly, and defrost before ice builds up much. So the full method is: unplug and empty, defrost if needed, wipe the interior and wash the shelves with a baking-soda or mild soapy solution, clean the door seal, exterior and accessible coils, dry everything, air it out, then plug back in and cool before restocking. Done this way, cleaning a mini fridge is straightforward and keeps it fresh and hygienic.

The short answer

Clean a mini fridge by unplugging it and emptying it first, then wiping out the inside and drying it. Unplug the fridge (safer, and it lets any frost melt), take out all the food and remove the shelves and bins, and if there is ice built up let it defrost with the door open rather than chipping at it. Wipe the interior, walls, floor, ceiling and door, with a mild solution of baking soda and warm water (about a tablespoon per liter/quart) or mild soapy water, which cleans and deodorizes, and wash the removable shelves and bins separately in warm soapy water, letting cold glass parts warm first. Clean the rubber door seal, getting into its folds, wipe the exterior, and gently dust or vacuum the rear coils if accessible. Wipe away any residue, dry everything thoroughly, and leave the door open to air out, then plug the fridge back in and let it cool to temperature before restocking. Leaving an open tub of baking soda inside keeps it fresh, and wiping spills promptly keeps future cleaning easy.
