Maintaining and cleaning a fridge does not have to take up much time, but it does make a big difference. Clean the inside every four to six weeks, check the door seals once a month and clean out the drip tray twice a year, and your fridge will keep working efficiently and last considerably longer. Neglect it and you end up with higher energy costs, unpleasant smells and, in the end, an expensive breakdown or an early replacement.
Why regular fridge maintenance pays off
A fridge runs day and night, 365 days a year. That calls for periodic maintenance, not as a luxury, but as the sensible choice for anyone who wants their appliance to run for as long and as cheaply as possible.
- Higher electricity use in poor condition: Dust on the condenser coils and a damaged seal force the motor to work harder. That translates directly into a higher energy bill.
- A longer service life: A fridge that is kept clean regularly does not have to work as hard. That spares the compressor and adds years to its life.
- Food safety: Bacteria and mould spores thrive in a damp, dirty fridge. Food residue left behind speeds up that growth and can make other food spoil sooner.
- Cooling performance maintained: A well-maintained fridge holds its temperature more steadily, which in practice also keeps the appliance's energy rating more stable.
How often should you clean a fridge?
There is no hard rule, but the schedule below is a good starting point for most households:
- Inside: a thorough clean every four to six weeks.
- Outside: a weekly wipe with a damp cloth prevents greasy fingerprints and grime.
- Rubber seal: check monthly for dirt, moisture and damage.
- Drip tray and the back (the condenser): inspect and clean at least twice a year.
- Smells or visible grime: act straight away, do not put it off.
For landlords who let a property with appliances included, a full check every six months is also a practical moment to document the condition of the appliance.
Step by step: cleaning the inside of your fridge
Cleaning the inside of a fridge is easiest if you tackle it systematically. Take everything out, work from the top down and dry it all thoroughly before you put it back.
- Step 1, switch the fridge off. Pull out the plug or turn the appliance to setting 0. Then take out all the contents and put anything perishable in a cool bag for the time being.
- Step 2, take out the drawers, shelves and door racks. Wash these separately in the sink with warm water and washing-up liquid. Let them come up to room temperature before you take them out of a cold fridge, otherwise the glass can crack from the difference in temperature.
- Step 3, clean the inner walls. Use lukewarm water with a small squirt of washing-up liquid, or dissolve a tablespoon of bicarbonate of soda in a litre of warm water. Bicarbonate of soda cleans well and neutralises smells at the same time.
- Step 4, avoid harsh products. Scouring pads, bleach or oven cleaner damage the plastic and can leave residues behind that come into contact with food. Keep it mild.
- Step 5, dry everything properly. Use a clean tea towel or a microfibre cloth. Moisture collecting in corners and seams is a breeding ground for mould. Only once everything is dry do you put the shelves and the contents back.
Cleaning and maintaining the rubber seal
The rubber seal, also called the door gasket or the fridge seal, is one of the most underrated parts of the appliance. It is crucial all the same: a poor seal means cold air escapes and the motor is constantly compensating.
- Cleaning: Wipe the rubber with a damp cloth and mild soapy water. Pay extra attention to the folds and lips where dirt and moisture build up.
- Checking: Do the banknote test, closing the door on a sheet of paper. If the sheet pulls away easily, the door is no longer sealing properly.
- Small cracks or distortion: Fine splits in the rubber lead to a loss of cold. If the damage is considerable, either the seal or the appliance needs replacing.
- Keeping it supple: After cleaning, rub a little petroleum jelly into the rubber. This stops it drying out and extends the life of the seal.
The back and the drip tray: the maintenance everyone forgets
The back of a fridge is rarely seen and therefore rarely cleaned. Yet this job shows up directly in your energy use.
- Condenser coils: Behind or underneath the fridge sit the condenser coils. Dust building up on them insulates the heat exchange, so the compressor has to run harder and for longer. Vacuum or brush them clean carefully twice a year.
- Cleaning the drip tray: Underneath most fridges sits a drip tray that collects the waste water. That tray can hold standing water, mould and bacteria. Take it out, empty it and clean it with mild soapy water.
- Clearance around the appliance: Allow at least five centimetres of space at the back and at the sides. Without enough air circulation the heat cannot escape properly, which puts extra strain on the appliance.
The same rules apply to a fridge freezer, with extra attention for the freezer drawer or the freezer compartment, where ice builds up faster if the seal is not closing properly.
Tackling unpleasant smells in the fridge
A fridge that smells bad is unpleasant, but almost always fixable. In most cases the cause is a combination of dried-on food residue, forgotten items at the back and damp shelves that were never dried properly.
- A thorough clean first: Smells do not disappear by setting something against them, so clean the fridge thoroughly first, as described in the step-by-step above.
- Bicarbonate of soda: Stand a small dish of bicarbonate of soda at the back of the fridge. It absorbs smells effectively and costs very little. Replace it every two to three months.
- Activated charcoal: Works a little more powerfully than bicarbonate of soda and is sold as odour granules made specially for fridges.
- Lemon or coffee grounds: Half a lemon or a dish of coffee grounds will neutralise smells temporarily and add a fresh note. Handy as a short-term fix.
- Close it up dry: Dry everything properly after every clean. Moisture is the main cause of smells that keep coming back.
When is maintenance no longer enough and do you need a new fridge?
Regular maintenance extends the life of a fridge considerably, but at a certain point replacing it is the wiser choice.
- The fridge no longer cools well enough: If the temperature will not stay stable despite correct maintenance, that points to a problem in the cooling system.
- The motor runs constantly: A compressor that never switches off is working too hard and using a lot of electricity. That is often a sign of a leaking cooling system or a weak compressor.
- Visible damage: Cracks in the cooling circuit, condensation on the outer wall or ice forming in places where it should not be are all warning signs.
- An age of over 10 to 12 years: Older fridges are generally a good deal less energy efficient than modern models. Over time, the saving on your energy bill can fully offset the cost of a new appliance.
- Repair costs above 50%: Is the repair quote more than half the price of a comparable new appliance? Then replacing it is almost always the better investment.

Frequently asked questions
How do I clean the inside of my fridge without chemicals?
Dissolve a tablespoon of bicarbonate of soda in a litre of lukewarm water and use it as an all-purpose cleaner for the inner walls, the shelves and the drawers. Bicarbonate of soda is mild yet highly effective, completely safe for contact with food and neutralises smells at the same time. Wiping it off with a damp cloth and drying it properly is all it takes.
How often should I clean the condenser on my fridge?
Twice a year is the recommended frequency. If you have pets or a dusty environment, four times a year is wiser. Dust on the condenser coils noticeably increases electricity use.
My fridge smells bad, what can I do?
Start with a thorough clean of the inside: take out all the contents, wash the shelves and drawers, and clean the walls with a bicarbonate of soda solution. Dry everything completely. Then stand a dish of bicarbonate of soda or activated charcoal in the fridge as a permanent odour absorber. Check the drip tray underneath the appliance as well, as it is a common but forgotten source of nasty smells.
How do I know whether the door seal on my fridge is still in good condition?
Use the banknote test: close the fridge door on a sheet of paper (or a banknote) and pull it out gently. If the sheet offers resistance, the door is sealing properly. If it slides out easily, the seal is too loose and the fridge is losing cold air. Check visually as well for small cracks, distortion or spots where the rubber is coming away.
Can I switch a warm fridge straight back on after cleaning it?
Yes, you can, provided the appliance has not gone through a complete change of temperature. If you have had the fridge switched off for hours and it has come up to room temperature, you can simply switch it back on. Do wait until the inside is completely dry before you put the plug back in.
How long does a fridge last with good maintenance?
A well-maintained fridge lasts 15 to 20 years on average. Without maintenance, that average life drops back to 10 to 12 years. Cleaning the condenser regularly, keeping the seal supple and emptying the drip tray are the three maintenance steps that do most for the life of the appliance.
Is it worth having an old fridge repaired?
That depends on its age and on the repair costs. If the appliance is more than ten years old and the repair costs more than fifty per cent of the purchase price of a comparable new model, replacing it is almost always the wiser move. A new, energy efficient model with a high energy rating also lowers your electricity costs, which earns part of the investment back. Feel free to look at our current range of fridges at sharp prices for comparison.
Conclusion
Maintaining and cleaning a fridge is not complicated work, but it does need to be done regularly. With a few simple jobs, cleaning the inside periodically, checking the seal, keeping the condenser free of dust and emptying the drip tray, you will get considerably more years out of your appliance and save on your energy bill. If the fridge reaches the end of the line all the same, Pro Witgoed offers an honest alternative: affordable Heinner fridges with a five-year warranty, without needless extra costs.
