How to Clean Fridge Coils – 5 Best Tricks and Tips (Home Guide)

Why Cleaning Fridge Coils Matters More Than You Think

Fridge running louder than usual? Food not as cold as it should be? It might be time to clean your fridge coils. Hidden away at the back or beneath your fridge, these coils help dissipate heat. But when they're caked in dust, pet hair or grime, your fridge must work twice as hard—leading to higher energy bills and potential breakdowns.

Luckily, it’s an easy job you can do at home. Below are 5 proven tricks and tips for cleaning fridge coils the right way, without damaging anything. Whether you’re a homeowner in Hertfordshire or managing a rental flat, these tips will help your fridge last longer and perform better.

1. Unplug and Locate the Coils Safely

Before anything, safety first: unplug your fridge from the mains. Then, locate the coils — they’re either:

• At the back (vertical metal grids)
• Or underneath (accessed via a bottom front or rear panel)

If they’re underneath, remove the grille or kick plate carefully using a flathead screwdriver. Don’t yank — just pop it loose gently.

2. Use a Coil Cleaning Brush

A coil cleaning brush is specially designed for this job. It fits into tight spaces and helps you loosen stubborn dirt without damaging the metal.

• Gently brush along the coils
• Start from top to bottom to let debris fall downward
• Repeat 2–3 times for each side

3. Vacuum Thoroughly with a Hose Attachment

Once the dust is loosened, grab your vacuum cleaner with a hose or crevice attachment. Carefully vacuum all around the coils, motor fan, and floor underneath. Take care not to poke or bend the coils—these are delicate components.

This not only removes dirt but helps reduce noise caused by fan strain.

4. Wipe Down the Base and Grille

Dust and crumbs can collect at the bottom of the fridge cabinet. Wipe the surrounding surfaces using a damp microfibre cloth. Clean the grille or kickplate before reinstalling it — this keeps airflow unrestricted.

For stuck-on grime, use mild washing-up liquid. Never spray water directly into the coil area.

5. Repeat Every 6 Months

Most homeowners forget about fridge coils altogether—but it’s a small task that makes a big difference. Set a reminder to clean them at least every 6 months. More often if you have pets, as fur tends to clog airflow quickly.

You’ll see improvements in cooling, noise, and even electricity bills.

Signs Your Coils Might Need Cleaning

• Your fridge motor is running non-stop
• Excess heat behind or beneath the fridge
• Unusual noise from the motor fan
• Food not cooling evenly or going off too soon

Quick Tip for Landlords and Tenants

If you're renting or letting a property, cleaning fridge coils between tenancies can prevent unexpected repair costs. A quick 15-minute clean could save you hundreds in maintenance or early appliance replacement.
