How to Clean Inside of Refrigerator | The Complete Deep-Clean

The right order takes about an hour, and doing it every three to six months keeps odors, spills, and bacteria from building up. Here’s the full process, from unplugging to the moment food goes back in.

What You Need Before You Start

Gather everything first so you’re not hunting mid-task. Hot water, mild dish soap, baking soda, and clean towels cover nearly the whole job. A spray bottle helps for the baking soda solution.

• Mild dish soap — safe on every interior surface, including gaskets
• Baking soda — mix 1 to 2 tablespoons into 1 quart of warm water for a gentle deodorizing cleaner
• Clean towels or microfiber cloths — for washing, rinsing, and drying
• A cooler with ice — to hold perishables while the fridge is empty
• Liquid bleach — only if you’re sanitizing after cleaning, using 1 tablespoon per gallon of water

Set the temperature control to OFF and unplug the unit first, per manufacturer guidance.

The Step-by-Step Cleaning Process

Start by emptying everything. Throw out expired, spoiled, leaking, or recalled food as you go, and move perishables you’re keeping into the cooler. Then remove every removable part — shelves, drawers, bins, and the ice storage tray.

Let glass and plastic parts warm to room temperature before washing. Cold glass dropped into hot water can crack — that’s the most common way people break a shelf. Wash these parts by hand in hot, soapy water, then set them aside to dry completely.

For the empty interior, work top to bottom: ceiling, walls, back panel, bottom, then doors. Use hot soapy water or the baking soda solution on a wrung-out cloth, so you’re not leaving puddles near light bulbs, controls, or electrical parts. Rinse with clean water if you used soap, then dry everything with a clean towel before replacing shelves.

Cleaners like the best cleaner for inside refrigerator can handle tough grease, but the baking soda route works for most messes without residue.

Sanitizing and Door Gasket Care

After cleaning, sanitize only if someone was sick or raw meat leaked. Use 1 tablespoon of liquid bleach in 1 gallon of water, applied to clean surfaces — never skip the cleaning step first, because bleach can’t penetrate grime. Rinse and dry after.

Door gaskets need special handling. On most models, use only mild dish soap and water, then dry fully — bleach or harsh cleaners can dry out and crack the rubber seal, breaking the airtight closure that keeps your fridge efficient. Some manufacturer guides say to use water only on the seal, since soap residue can degrade it over time.

How Often Should You Clean It?

Every three to six months keeps the interior manageable. A quick monthly wipe-down of spills as they happen cuts down the deep-clean workload considerably.

What to Avoid and What Comes After

The most common mistakes are easy to dodge once you know them. Washing cold glass in hot water cracks it. Too much water near electrical parts shorts them out. Bleach on gaskets ruins the seal. And returning food before the fridge re-cools risks bacterial growth.

• Don’t plug back in until everything is dry and in place
• Skip harsh chemicals on seals, gaskets, and any surface the manual prohibits

Once the interior is clean, pull the unit out and vacuum or dust underneath. Unplug, then use a coil brush under the kick plate to remove dust from the condenser coils — this keeps the fridge running efficiently and extends its life.

Check the manual’s guidance for your model; most have a temperature display or a setting that shows current interior temperature.
