How to Clean Refrigerator Inside: A Complete Step-by-Step Guide

Your refrigerator works hard every day to keep your food fresh — but it also collects spills, crumbs, and bacteria over time. A thorough interior clean every 3 months keeps your fridge hygienic, odor-free, and running efficiently. Here's exactly how to do it.

What You'll Need

• Microfiber cloths
• Non-scratch scrub sponge
• Spray bottle
• Baking soda
• White vinegar
• Dish soap
• Warm water
• A cooler (to store food during cleaning)

Step 1: Empty the Refrigerator

Remove all food and place perishables in a cooler with ice. This is also a great time to check expiration dates and discard anything past its prime. Remove all shelves, drawers, and removable bins.

Step 2: Clean Removable Parts

Wash shelves, drawers, and bins in the sink with warm soapy water. For stubborn stains, soak in a solution of warm water and a few tablespoons of baking soda for 10 minutes, then scrub with a non-scratch sponge. Rinse and dry completely before replacing — moisture can encourage mold growth.

Important: Let glass shelves come to room temperature before washing in warm water to prevent cracking from thermal shock.

Step 3: Clean the Interior Walls, Ceiling, and Floor

Mix 1 tablespoon of baking soda per 1 quart of warm water in a spray bottle. This solution is food-safe, deodorizing, and effective on grease and spills. Spray all interior surfaces and wipe with a microfiber cloth.

For stubborn sticky spots, apply a baking soda paste directly and let sit for 5 minutes before scrubbing.

Step 4: Clean the Door Shelves and Gasket

Wipe down door shelves with the baking soda solution. Pay special attention to the rubber door gasket (seal) — use a small brush or old toothbrush to clean the folds where mold and grime accumulate. Wipe dry with a microfiber cloth.

Step 5: Deodorize

Once clean, place an open box of baking soda on a shelf to continuously absorb odors. Replace every 3 months.

Step 6: Replace Shelves and Food

Make sure all shelves and drawers are completely dry before replacing. Return food, organizing as you go — keep raw meat on the lowest shelf, dairy in the coldest spot, and produce in the crisper drawers.

Maintenance Tips

• Wipe up spills immediately before they dry and harden.
• Do a quick wipe-down of shelves weekly.
• Deep clean every 3 months.
• Keep an open box of baking soda inside at all times to control odors.
