How To Maintain Your Refrigerator & Keep it Clean

The refrigerator is one of the most costly items in the home so maintain it well to keep cash in your pocket.

The most essential piece of equipment in the kitchen, make sure your fridge is running efficiently for better food storage and to keep energy costs down.

Give it enough room by allowing at least a 10mm gap at the sides and 20mm behind. If the fridge is in direct sun, install a blind to screen it. Better still, ventilate the fridge space to the roof void or through outside walls.

Clean it inside and out every four to six months, working from the top down and cleaning one shelf or area at a time. Wipe the interior with a mild detergent solution or bicarb soda.

Wash removable shelves in the sink with warm water and detergent, but let glass shelves come to room temperature first to avoid cracks.

Clear the drain hole at the base of the fridge and wipe the door seals, taking care to clear all dirt from the grooves.

Wipe the coils and around the motor every three months as dust can cause the unit to run poorly. Unplug the fridge, pull it out and use the vacuum cleaner’s brush attachment.

Keep it level to make it efficient. Raise or lower the feet or castors using an adjustable wrench, or turn the levelling screws with a shifter. Use a spirit level to ensure that the fridge is balanced.

Check door seals twice a year to keep food fresh and energy costs down. Close the door on a sheet of paper then try to pull the paper out. If there’s little resistance, the seal isn’t working. Coat the flat surface with petroleum jelly, or completely replace a stiff or cracked seal.

Keep the freezer well stocked

A well-stocked freezer isn’t just good news for mealtimes, it also keeps your freezer running at maximum efficiency as there’s less circulating air that has to be cooled. Fill empty spaces with containers of water. They will not only improve your freezer’s performance but also help to keep the contents cold for longer in the event of a power cut.

Choosing a new model

Refrigerators are switched on and running 24 hours a day, all year long. They account for about 20% of the electricity used in the average home, so it definitely pays to make sure they run as efficiently as possible.

When you need to replace your fridge, choose one with the highest energy rating you can afford and look for the energy-saving logo. The most efficient new models can save about two-thirds of the power used by a 10-year-old fridge.

Frequently Asked Questions

Why is it important to maintain your refrigerator regularly?

Regular maintenance of your refrigerator ensures it operates at peak efficiency, extends its lifespan, and keeps your food fresh for longer. It also helps prevent unpleasant odours and the growth of harmful bacteria, thereby promoting better health and food safety.

How often should I clean my refrigerator?

It's recommended to clean your refrigerator thoroughly every three months. However, consider wiping down high-touch areas and checking for expired food weekly for optimal performance and hygiene. A regular cleaning schedule helps prevent the build-up of dirt and bacteria.

What are some basic steps to clean my refrigerator?

Start by unplugging the refrigerator and removing all food and shelves. Clean the interior with a mixture of warm water and mild dish soap, then wipe it dry. Wash the shelves and drawers separately, let them dry, then replace them. Finally, check the food before putting it back, discarding anything past its expiration date.

Should I defrost my refrigerator during cleaning?

If your refrigerator doesn't have an auto-defrost function, you should defrost it during cleaning. Defrosting removes built-up ice that can reduce the efficiency of your fridge and take up valuable storage space. Remember to place a towel to absorb the meltwater.

How can I control bad odors in my refrigerator?

To control bad odours, make sure to clean up spills immediately, throw away spoiled or expired food regularly, and keep your food in sealed containers. You can also place an open box of baking soda inside the fridge to absorb unpleasant smells.
