By defrosting your fridge freezer, you can improve its efficiency and clear space for extra food. Our guide on defrosting highlights some common mistakes and reveals how often the job needs doing.

If you're having problems with your fridge freezer, the issue might not be a mechanical one. A fridge freezer stuffed with more ice blocks than food won't work as well as it should, which is why defrosting is so important.

Many modern fridges and freezers arrive with an auto-defrost setting that can save you some time, but older alternatives aren't always so well-equipped. Keep scrolling for some top tips on defrosting your fridge freezer.

Why should you defrost a fridge freezer?

Unlike frost-free models, static fridge freezers need to be manually defrosted occasionally. It might not be a particularly fun task, but it's an important one.

For one, defrosting your fridge freezer will improve its efficiency, as thick ice blocks can limit the appliance's effectiveness at keeping your food at a specific temperature.

It can help with nasty smells, too. By defrosting a fridge freezer, you'll be able to scrub down the sides of the fridge freezer that might have previously been unreachable. You'll be able to squeeze more food into an ice-free fridge freezer, too.

How to defrost a fridge freezer quickly

If you open your fridge freezer and see chunks of ice and frost gathering in the corners of the shelves, it's a good time to defrost your fridge freezer.

1. Plan in advance

It makes sense to plan ahead. Knowing when you're going to get the job done means you can eat your freezer food rather than try and find a place to store it all on the day. Cleaning your freezer on a cooler day means the food you've removed will stay cold for longer.

If you need a place to store food while defrosting your fridge freezer, use a cooler box. After the fridge freezer is switched off, it won't take long for the temperature to warm up, even if the door stays closed. Once you switch the appliance back on, our tests have found that the fastest models will take several hours to cool down, while the slowest models will take well over 12 hours.

2. Turn it off

The first step is an obvious one – turn off your fridge freezer and let it defrost on its own. Despite what you may have read elsewhere, it's best to avoid using a hairdryer or other electrical products to speed up the process of removing ice as it poses a safety risk.

3. Have some towels ready

It won't come as a surprise to hear that defrosting a fridge freezer might leave your kitchen floor a little wet. Layer some towels around the base of the fridge freezer to soak it all up.

4. Take care when removing ice

If you're hammering away at an ice block at the back of your fridge freezer, make sure you don't accidentally chip the back of the freezer wall. Doing so could potentially cause the refrigerant to leak out. Don't use a sharp implement, either – try using a plastic ice scraper instead.

5. Cleaning up

After all of the ice has thawed, finish off by cleaning the inside of the fridge freezer with some warm water and a drop of detergent. You can wipe it clean with dry towels before you switch it back on and put your food back inside.

How often should you defrost a fridge freezer?

It's time to defrost your fridge freezer when frost and ice are interfering with its normal operation.

How often you need to defrost your fridge freezer can depend on its size and what type of fridge freezer you own. Obviously, fridge freezers with auto-defrost settings are easier to deal with.

There are ways to defrost a fridge freezer that don't need you to turn the appliance off completely.

One method involves boiling some water, pouring that water into a baking tray or pan and placing that in the freezer when it's empty. The steam from the hot water will work its way around the shelves and help to melt the ice faster.
