How to Clean Your Fridge Properly: A Practical Australian Guide

Before you grab the sponge, it helps to know what you're saving by doing regular cleaning yourself. Most fridge problems that require a professional callout stem from neglected maintenance: blocked drains, dirty condenser coils, and failing door seals. Here's what you can expect to pay if things go wrong.

With 205 fridge repair businesses across Australia averaging 4.4 out of 5 stars, finding a reliable technician isn't hard. But a 30-minute clean every month can prevent most of these callouts entirely.

A proper fridge clean starts with everything out. This takes about 10 minutes and sets you up for a thorough job rather than wiping around obstacles.

Remove all food and check expiry dates

Pull everything out and place perishables in an esky or insulated bag with ice packs. In Australian summer conditions, food left at room temperature for over two hours enters the danger zone (above 5°C), so work quickly or plan your clean for a cooler day.

Check every jar, container, and packet. That half-used jar of korma paste from 2024? Bin it. Expired condiments are the number one source of fridge odour because they slowly leak, drip, and ferment on shelves you can't easily see.

Remove all shelves, drawers, and door bins

Glass shelves, crisper drawers, and plastic door bins should all come out. Most modern fridges from brands like Westinghouse, Samsung, and Fisher & Paykel use clip-in shelf systems. Lift the front edge slightly and slide forward to release.

Soak shelves and drawers in the kitchen sink or laundry tub with warm water and a tablespoon of bicarbonate of soda. Let them sit while you clean the interior.

With the fridge empty, you can actually reach every surface. This is the core of the clean and takes roughly 15 minutes.

The best cleaning solution for fridge interiors

Mix two tablespoons of bicarbonate of soda into one litre of warm water. This is mildly alkaline, which neutralises acidic food spills and odours without leaving a chemical residue. Avoid bleach, vinegar (it can damage rubber seals over time), and commercial kitchen sprays that leave fragrance residues your food will absorb.

Use a clean microfibre cloth, not a scouring pad. Abrasive cleaners scratch the interior lining, and those scratches harbour bacteria that become harder to remove with each clean.

Pay attention to the drain hole

Every fridge has a small drain hole at the back of the interior, usually at the base of the rear wall. This channels condensation to the drip tray underneath. If it's blocked, water pools inside the fridge, creates ice buildup, and eventually causes that mysterious puddle on your kitchen floor.

Clear the drain with a cotton bud or a pipe cleaner. If it's heavily blocked, use a turkey baster filled with warm water to flush it through. You should hear water trickling into the drip tray below.

Wipe the door seal thoroughly

The rubber gasket around your fridge door is a magnet for crumbs, sticky residue, and mould. Fold your microfibre cloth around a butter knife to get into the crevices of the seal folds. Black mould in these folds is common in humid climates along the Queensland and NSW coasts.

A damaged or dirty seal forces the compressor to work harder, increasing energy consumption by up to 20%. If the seal is cracked, torn, or no longer holds a piece of paper firmly when you close the door on it, it needs replacing. Replacement seals for popular brands like LG, Electrolux, and Whirlpool cost $40–$120 for the part, or a technician can fit one during a standard service call.

This is the single most impactful maintenance task most people skip. Dusty condenser coils force your compressor to run longer and hotter, shortening your fridge's lifespan and driving up electricity costs.

Where to find the coils

On most Australian-market fridges (Samsung, LG, Westinghouse, Fisher & Paykel), the condenser coils are either at the back of the unit or behind a kick plate at the bottom front. Pull the fridge away from the wall carefully. If it's on tiles, place old towels under the front feet to avoid scratching.

How to clean them

Use a vacuum cleaner with a crevice attachment to remove dust, pet hair, and lint from the coils. Follow up with a long-handled coil brush (available from Bunnings for around $15) to dislodge compacted dust. The whole process takes about 10 minutes.

A fridge with clean coils runs more efficiently and can last towards the upper end of its 6 to 13 year lifespan. Neglected coils are one of the main reasons compressors fail prematurely, and compressor replacement is the most expensive fridge repair, often exceeding $400.

Locate and empty the drip tray

The drip tray sits underneath the fridge, usually accessible by removing the front kick plate. It collects condensation that drains from the interior. In normal operation, this water evaporates from the heat of the compressor. But in humid Australian conditions (particularly in Darwin, Cairns, and coastal Queensland), the tray can overflow or develop a slimy biofilm that smells terrible.

Slide the tray out carefully, empty it, and wash it with warm soapy water. A splash of white vinegar in the rinse water helps prevent mould regrowth. Replace it and snap the kick plate back on.

Wipe down the exterior

For stainless steel fridges (common on Miele, Bosch, and Smeg models), wipe in the direction of the grain using a damp microfibre cloth, then buff dry. Avoid circular motions, which leave visible swirl marks. A tiny amount of baby oil on a dry cloth restores shine without the cost of specialised stainless steel sprays.

For painted or textured finishes, warm water and a mild dish detergent are all you need. Clean the door handles thoroughly as they're one of the most touched surfaces in any kitchen.

Consistency matters more than intensity. A quick monthly wipe-down prevents the kind of grime buildup that turns into a two-hour scrubbing session.

Following this schedule keeps your fridge running efficiently and reduces the chance of unpleasant surprises. A fridge that's cleaned regularly also uses less energy, as the compressor doesn't have to compensate for blocked airflow or struggling seals.

Regular cleaning handles most of what keeps a fridge healthy. But some problems go beyond what a cloth and bicarbonate of soda can fix.

Signs you need a technician

Call a professional if you notice any of the following:

• The fridge isn't maintaining temperature below 5°C despite clean coils and a good seal
• Unusual clicking, buzzing, or humming that doesn't stop
• Ice forming excessively on the back wall even after clearing the drain
• The compressor runs constantly without cycling off
• Water leaking from underneath that persists after cleaning the drip tray and drain

Highly rated businesses like Sydney Appliance Service (4.8 stars, 1,057 reviews), Nationwide Appliance Repairs (4.6 stars, 2,030 reviews), and EPL Appliance Repair (4.9 stars, 723 reviews) service all major brands including Electrolux, LG, Samsung, Miele, and Fisher & Paykel. Around 74% of Australian fridge repair businesses offer emergency or same-day service, which is reassuring if your fridge fails on a Friday afternoon in February.

Ark Appliance Repairs provides a 90-day service guarantee and 12-month part warranty. Alpha Appliance Repairs offers a 12-month parts warranty and 100% workmanship guarantee. Norwest Appliance Service also provides a 12-month guarantee on parts and repairs. These warranties mean that if the same fault returns, you won't pay twice.

The general rule from industry professionals: if a repair costs more than 50% of what a new fridge would cost, and your fridge is over 10 years old, replacement is usually the better investment. For a fridge under 10 years old, repair is almost always more economical.
