How to Remove Mould from Refrigerator: A Complete Guide to Cleaning, Prevention and Safe Food Storage

A refrigerator is designed to keep food fresh, but if moisture, spills, spoiled food, or long periods of inactivity occur, mould can start growing inside. Mould not only creates unpleasant odours but can also contaminate food and affect the hygiene of your kitchen.

If you've noticed black, green, white, or fuzzy patches inside your appliance, don't panic. Learning how to remove mould from refrigerator surfaces properly can restore cleanliness and prevent the problem from returning. In this guide, we'll explain how to clean a mouldy fridge safely, the supplies you'll need, and practical tips to keep mould and mildew away for good.

Why Does Mould Grow Inside a Refrigerator?

Many people assume refrigerators are too cold for mould growth. While low temperatures slow down mould development, they don't completely stop it. Mould thrives in moist environments, especially in refrigerator door seals, vegetable drawers, drainage holes, and forgotten food containers.

Common reasons include:

• Expired or spoiled food can release moisture and spores that encourage mould growth inside the refrigerator.
• High moisture levels inside the fridge create a damp environment, and mould needs to spread quickly.
• Poor air circulation allows humid pockets to form, especially in corners and drawers where mould can develop.
• Spilt liquids left unattended provide a food source and moisture, making mould more likely to appear.
• Dirty door gaskets trap crumbs, moisture, and grime, which makes them a common spot for mould buildup.
• Power outages or unused refrigerators can let food spoil and moisture settle, creating ideal mould conditions.
• Improper temperature settings may keep the fridge too warm, allowing mould and bacteria to grow faster.

Understanding the cause helps prevent the issue from recurring after cleaning.

Signs Your Refrigerator Has Mould

Before learning how to clean mould in refrigerator compartments, it's important to identify the warning signs.

Common signs include:

• Black, green, white, or grey spots on shelves
• Fuzzy patches on food containers
• Musty or damp smell
• Discolouration around rubber door seals
• Visible mildew in drawers and corners
• Persistent odours despite regular cleaning

If you notice any of these signs, it's time to clean the refrigerator thoroughly.

Is Mould in the Refrigerator Dangerous?

Mould exposure can be harmful, especially for children, elderly family members, and people with allergies or respiratory conditions. While not every mould species is toxic, it is best to remove any visible growth immediately.

Potential risks include:

• Food contamination: Mould spores can spread to nearby food items, making them unsafe to eat even if the mould is not directly visible on them.
• Allergic reactions: Mould exposure may trigger sneezing, itching, watery eyes, or skin irritation in sensitive individuals.
• Respiratory irritation: Breathing in mould spores can cause coughing, throat irritation, or breathing discomfort, especially for people with asthma or allergies.
• Unpleasant odours: Mould often produces a damp, musty smell that can spread throughout the refrigerator and affect stored food.
• Faster spoilage of stored food: Excess moisture and mould growth can cause food to deteriorate more quickly, reducing freshness and shelf life.

For this reason, knowing how to remove mould from fridge interiors safely is essential for maintaining a healthy kitchen environment.

Supplies You'll Need to Clean a Mouldy Refrigerator

Before starting the cleaning process, gather all necessary supplies. Using the right cleaning materials ensures effective mould removal without damaging refrigerator surfaces.

The table below lists the recommended cleaning supplies and their purpose during mould removal.

How to Remove Mould from a Refrigerator Step by Step

If you're wondering how to clean a mouldy refrigerator properly, follow these steps carefully.

Step 1: Unplug the Refrigerator

For safety and easier cleaning, switch off and unplug the refrigerator before beginning.

Step 2: Remove All Food Items

Take out all food products and inspect them carefully.

Discard:

• Expired food, mouldy fruits and vegetables
• Contaminated leftovers
• Food with unusual odours

If mould is visible on nearby items, dispose of them to avoid cross-contamination.

Step 3: Remove Shelves and Drawers

Take out removable shelves, bins, and drawers.

Wash them separately using warm water and mild dish soap.

Allow them to dry completely before reinstalling.

Step 4: Prepare a Cleaning Solution

One of the safest methods for how to clean mould from fridge interiors is using vinegar.

Mix:

• Equal parts white vinegar and water

Alternatively:

• 1 tablespoon of baking soda in 1 litre of warm water

Avoid mixing bleach with other cleaning chemicals.

Step 5: Clean All Interior Surfaces

Spray the cleaning solution generously onto:

• Shelves
• Walls
• Drawers
• Door compartments
• Interior ceiling

Let it sit for 10–15 minutes before wiping.

This helps loosen mould and mildew deposits effectively.

Step 6: Scrub Mould-Affected Areas

Use a soft sponge or toothbrush to clean stubborn spots.

Pay special attention to:

• Corners
• Drawer tracks
• Rubber seals
• Drain channels

This step is particularly important when learning how to clean mould in a fridge thoroughly.

Step 7: Clean the Door Gasket

The rubber gasket is one of the most common mould growth areas.

Carefully clean all folds and creases using a toothbrush dipped in vinegar solution.

Wipe dry afterwards.

Step 8: Dry the Refrigerator Completely

Mould loves moisture.

Use dry microfiber cloths to remove all remaining water before reassembling the refrigerator.

Step 9: Reassemble and Restart

Return all shelves and drawers.

Plug the refrigerator back in and allow it to cool before restocking food.

Best Cleaning Solutions for Refrigerator Mould Removal

Different cleaning agents work well depending on the severity of mould growth.

The comparison below highlights common refrigerator-safe cleaning options.

Cleaning Solution	Effectiveness	Safe for Refrigerator	Odour Removal
White vinegar	Excellent	Yes	Excellent
Baking soda solution	Good	Yes	Excellent

How to Clean Fungus from Fridge Door Seals

Many homeowners struggle with fungus hidden inside door gaskets.

To clean fungus effectively:

1. Open the gasket folds gently.
2. Spray the vinegar solution inside.
3. Leave for 10 minutes.
4. Scrub using an old toothbrush.
5. Wipe clean.
6. Dry thoroughly.

Regular cleaning prevents mould from returning to these difficult-to-reach areas.

How to Clean Mildew from Refrigerator Drawers

Mildew often forms in vegetable compartments because of trapped moisture. Mildew is a thin layer of fungus that grows in damp, poorly ventilated areas and usually appears as white, grey, or black patches.

To remove mildew:

• Remove drawers completely.
• Wash with warm water and soap.
• Apply the vinegar solution.
• Scrub affected areas.
• Rinse thoroughly.
• Dry before reinstalling.

Proper drying is crucial for preventing future mildew growth.

How to Prevent Mould from Returning to Your Refrigerator

Cleaning solves the immediate problem, but prevention is equally important.

Follow these simple habits:

• Keep Food Covered: Store leftovers in airtight containers.
• Check Expiry Dates Weekly: Remove spoiled food before mould spreads.
• Wipe Spills Immediately: Liquid spills create ideal conditions for mould growth.
