How to Clean Refrigerator: Easy Step-by-Step Guide

A dirty refrigerator doesn't just look unpleasant,  it can harbor harmful bacteria, cause unpleasant odors, and even affect the taste of your food. Knowing how to properly clean refrigerator shelves, drawers, and seals is essential for maintaining a healthy kitchen and extending the lifespan of your appliance. At BlueStars Parts, we specialize in providing genuine replacement parts and expert guidance to help you keep your refrigerator running efficiently and fresh.

1. How Often Should You Clean Your Refrigerator?

You should clean refrigerator surfaces lightly every week and do a deep clean every 3-4 months to keep food safe, prevent odors, and maintain cooling efficiency. Clean it sooner if you notice clear signs of buildup, such as:

• Sticky shelves, drawers, or door handles

• Weird smells that do not go away

• Water pooling under drawers or near the drip pan

• Expired food building up in the back of shelves

• Crumbs, stains, or residue around door seals

A weekly quick clean refrigerator usually includes checking leftovers, wiping spills, and sanitizing handles or door seals. Deep cleaning should involve removing all food, washing shelves and drawers, cleaning the interior walls, and vacuuming condenser coils if accessible. Homes with pets, children, or heavy refrigerator use may need more frequent cleaning.

2. What to Use to Clean a Refrigerator

Choosing the right cleaning products is just as important as knowing how often to clean. There are a variety of household cleaning products you can use to refresh your refrigerator, including dishwashing soap, warm water, and a vinegar solution - no fancy supplies needed. 

NOTE: Not all cleaning products are safe for your refrigerator. Using the wrong ones can damage interior surfaces, degrade seals, or contaminate your food. Always avoid: 

• Bleach or bleach-based cleaners: Not only can it harm materials in the fridge, but you also risk contaminating your food

• Abrasive scrubbers or scouring pads: Can scratch interior liners and glass shelves

• Window sprays (ammonia-based cleaners): Do not use commercial household cleaners containing ammonia, bleach, or alcohol to clean handles or interior surfaces

• Flammable fluids or wax-based cleaners: Do not use flammable fluids, cleaning waxes, concentrated detergents, or cleaners containing petroleum products on plastic parts, interior liners, or gaskets

• Baking soda on stainless steel exteriors: Baking soda should not be used on the exterior of stainless steel refrigerators

• Chloride-containing products on stainless steel: Never use chloride or cleaners with bleach to clean stainless steel

3. How to Clean a Refrigerator Step by Step

A clean refrigerator doesn't happen by accident, it takes a little method. Whether you're doing a quick monthly refresh or a full seasonal deep clean, following a clear step-by-step process ensures you don't miss any spots, avoid damaging your appliance, and get everything done safely and efficiently. Here's exactly how to clean refrigerator, do it from start to finish. 

Step 1: Unplug the refrigerator and remove all food

Before anything else, safety comes first. Cut the power at the circuit breaker and unplug the refrigerator before you begin. Place a towel on the floor to catch spills, move food into a cooler, and throw out expired or questionable items. This is also a great opportunity to take stock of what you have, toss anything with an off smell, odd texture, or past its use-by date. 

Caution: Never skip unplugging the fridge before a deep clean. You must unplug your refrigerator before attempting to clean it to avoid electric shock. Don't let food sit outside the fridge for more than two hours to prevent spoilage 

Step 2: Remove shelves, drawers, and door bins

Carefully take out the removable shelves and drawers. Set them aside to warm to room temperature. This step is critical, placing cold glass shelves directly into hot soapy water can cause them to crack from thermal shock. 

If your door bins or shelf brackets are cracked, broken, or no longer fitting properly, this is the right time to replace them. The W10900538 / W11239961 Refrigerator Door Shelf Bin (Right Side) is a compatible replacement for Whirlpool models (WRS325SDH, WRS311SDH), sold in a convenient pack of 2 - a simple fix that restores full storage capacity to your refrigerator door.

Step 3: Clean the refrigerator interior

Mix a quart of water with two tablespoons of baking soda. Dip a clean rag into the solution, then wipe the interior from top to bottom so drips fall onto areas you have not cleaned yet. Pay extra attention to hidden spots people often miss, such as corners, drawer tracks, the drain hole, shelf brackets, and under the glass shelf frame.

Tip: For stubborn stains, use a vinegar solution. For stuck-on food, spills, or lingering odors, use the baking soda mixture. If you notice small areas of mold, clean them with undiluted vinegar and a soft cloth, then avoid using that same cloth on other areas.

Step 4: Wash shelves, drawers, and bins

Once the shelves and drawers have come to room temperature, wash them in the sink. Do the same with the drawers and shelves - clean them with hot soapy water, and you can use vinegar or baking soda on tougher spills and stains. Rinse thoroughly and dry completely before putting them back. 

If your crisper drawer cover support is cracked or sagging, it's worth replacing it before reinstalling. The 241993101 Refrigerator Crisper Cover Support is a direct-fit replacement that keeps your crisper shelf stable and your produce properly stored - no more drooping covers or uneven shelves.

Step 5: Clean the refrigerator door gasket

The door gasket - the rubber seal running around the inside edge of the door - is one of the most neglected spots in any refrigerator. Using a microfiber cloth and a toothbrush dipped in a solution of 1 quart of warm water with 1 tablespoon of baking soda, gently wipe down the gaskets. This removes residue, mold, and mildew, while also reducing odors. Make sure to get into all the folds and crevices. 

Tip: Once clean, apply a thin layer of petroleum jelly along the length of the gasket. Over time, a rubber gasket loses moisture and becomes hard rather than soft. A tiny dab of petroleum jelly run along the entire surface of the seal can work wonders at restoring its moisture and capability. Do this once a year, and your seal gasket may last as long as the refrigerator itself. 

Step 6: Clean the exterior, handles, and top surface

After cleaning the inside of your fridge, take a few moments to clean the door seals, doors, and handles with a mix of mild dish soap and water. Then dry everything thoroughly, especially the door seals. Don't overlook the top of the fridge, which tends to collect grease and dust. 

Tip: If you have a stainless steel refrigerator, clean the doors with a specially formulated stainless steel cleaner to avoid streaks or residue. Always wipe in the direction of the grain for best results.

Step 7: Clean the condenser coils if accessible

The condenser coils are usually located at the back of the fridge or underneath it. When they collect dust, dirt, and debris, the fridge has to work harder to release heat. Signs of dirty coils may include hotter fridge sides, longer run times, weaker cooling, or a higher electric bill.

Unplug the refrigerator first, then use a coil brush or a vacuum with a brush attachment to remove buildup gently. If the fridge is against a wall, pull it forward carefully and ask someone to help if needed.

Caution: Do not force the fridge out or bend any tubing behind it. If the coils are hard to reach, skip this step or call a technician. 

Step 8: Clean the drip pan if your model has one

The drip pan sits underneath the fridge and collects condensation from the defrost cycle. If it is not cleaned regularly, standing water and residue can become a source of mold, musty smells, and unpleasant odors around the refrigerator.

If your model has a removable drip pan, remove the front kick plate, slide the pan out carefully, empty any standing water, and scrub it with hot soapy water. Dry it completely before putting it back.

Tip: Clean the drip pan about every three months, or sooner if you notice a musty smell near the bottom of the fridge.

Step 9: Dry everything before putting parts back

Before reassembly, make sure every surface is completely dry. Once you've finished cleaning, wipe the interior completely dry with a clean towel. Moisture left inside the fridge encourages mold growth and can cause new odors to form within days of your deep clean. 

Tip: Leave the fridge door open for 10-15 minutes to air dry naturally before plugging it back in and restocking. Reinstall shelves and drawers only once they are fully dry to the touch.

Step 10: Restock food safely and organize the fridge

Make sure the interior is dry before restocking. Keep older items at the front so they're used first. Group dairy, meats, and produce to avoid cross-contamination. Clear bins and labels help you see what you have and prevent food from getting lost in the back. 

Tip: Check that containers are clean before restocking. Label leftovers and store raw meats on the bottom shelf to avoid drips, this helps reduce the spread of bacteria and keeps your fridge food-safe. Set your refrigerator temperature to 40°F (4°C) or below and your freezer to 0°F (−18°C) for optimal food safety.

4. What are the common fridge cleaning mistakes?

Even with the best intentions, certain clean refrigerator habits can actually damage your appliance or compromise food safety. Here are the most frequent refrigerator cleaning mistakes you should avoid:

• Using harsh chemicals: Strong cleaners like bleach or ammonia can leave behind toxic residues and odors. Stick to food-safe options like warm soapy water or a simple vinegar solution.

• Ignoring the door gaskets: The rubber seals around the doors easily trap crumbs and can quickly grow mold. This weakens the seal and lets cold air escape.

• Cross-contamination: Wiping down your fresh produce bins with the same sponge used to clean up a raw meat spill spreads harmful bacteria. Always use separate or freshly sanitized cloths for different zones.

• Leaving interiors wet: Failing to thoroughly dry the shelves and drawers after washing them creates a damp environment that encourages new mildew and mold growth.

• Skipping the condenser coils: Forgetting to vacuum the dusty coils at the back or bottom of the fridge forces the compressor to work much harder, driving up your energy bills and shortening the lifespan of the appliance.

Over time, neglecting these cleaning steps can lead to permanent damage, such as torn door gaskets, cracked bins, or failing mechanical parts. If you notice any heavily worn or broken components while cleaning, you can find proper replacements at Refrigerator Parts to restore your fridge's efficiency.

5. FAQs

5.1. What is the best thing to clean the inside of a refrigerator with?

The best way to clean the inside of a refrigerator is with a mixture of warm water and mild dish soap, baking soda, or diluted white vinegar. These options are gentle, food-safe, and effective at removing stains, grease, and odors without leaving behind harsh chemical residue. Many appliance experts recommend using microfiber cloths or non-abrasive sponges to avoid scratching fridge surfaces. 

5.2. Is it safe to clean a refrigerator with vinegar?

Yes, it is generally safe to clean a refrigerator with white vinegar when diluted with water. Vinegar helps dissolve sticky spills, neutralize odors, and remove light bacteria buildup naturally. Most cleaning guides suggest mixing equal parts vinegar and warm water in a spray bottle for easy application. However, you should avoid using vinegar on certain sensitive materials if your refrigerator manufacturer advises against it. 

5.3. How long does it take to deep clean a fridge?

A full deep clean usually takes about 1–2 hours, depending on the refrigerator size and how dirty it is. The process includes removing food, washing shelves and drawers, wiping the interior, cleaning seals, drying components, and reorganizing everything afterward. Smaller fridges with regular maintenance may take less than an hour, while heavily soiled refrigerators can take longer. 

Knowing how to clean refrigerator does not have to be complicated. If you notice cracked drawers, damaged shelf supports, or worn-out door bins during cleaning, replacing those parts can help restore both organization and performance. For reliable replacement components compatible with many refrigerator models, BlueStars Parts offers a wide selection of refrigerator parts to help keep your appliance in top condition.
