How to defrost a chest freezer


Over time, frost will build up on the inside of your chest freezer – and you'll need to get rid of it. You should do it about once a year, or when the frost is more than half a centimetre thick. Defrosting can be slow, so follow these steps to help get it done faster.

What you'll need


Here's some bits you might need:

  • Cool boxes or another freezer, to store food while you’re defrosting
  • A kettle and some pans for hot water
  • Towels
  • A cleaning cloth and some soapy water
  • A wooden spatula or plastic scraper

Defrosting a chest freezer


Empty the freezer, and put your food into cool boxes or another freezer to keep it cold.


Unplug the freezer, then open the lid to start it defrosting.


If your freezer has a drain, open the drain cover and attach a hose adaptor. Feed the other end of the hose into a drain or bucket to collect water.


Fill some pans with warm water and put them in the bottom of the freezer – this will speed up the ice melting.


Use your scraper or wooden spatula to remove any large blocks of ice. Don't use metal ones, as these can scratch the inside of the freezer.


Use the cloth and a small bit of soapy water to clean up any stains.


Dry the freezer with towels so any leftover water doesn't freeze again inside it.


If your appliance has a drain, remove the hose adapter and put the the drain cover back on.


Plug the freezer back into the mains and turn it on.

Once it's all done, you can start to put your food back into it, as long as it's still frozen. If any food has defrosted, you shouldn't try to re-freeze it – but should cook it instead.
