How to Defrost a Freezer Properly

It's hard not to notice thick layers of frost that develop on foods and the walls of your freezer, which prompts many people to wonder what is the best way to defrost a freezer. Frost can cause freezer burn, which makes foods taste bland and develop an unpleasant texture. It can also make your freezer run less efficiently, leading to higher electricity bills. Those that own an automatic defrost freezer don't have to worry about this problem as much, but those with a manual defrost freezer can remedy the situation easily enough.

Automatic defrost freezers prevent frost from building up by heating the refrigerator coils inside the unit, which melts any ice that has accumulated on them. If your unit doesn't have an automatic defrost, you can defrost it manually with minimal effort. Learn more below!

The easiest way to defrost your freezer is to simply unplug the unit and leave the freezer door open. This allows warm air to get inside and melt the ice to water, which you can easily wipe up with a towel. To use this method, first take out all of the food you have in your freezer, and either place it in a cooler with ice, or another freezer if you have one. Many people find that this is a good time to throw away old foods that are too freezer burned to use anyway.

Next, either turn off or unplug your freezer and leave the door open. We suggest covering the bottom of the freezer with old towels, newspapers, or even a small pan to collect the water as it melts. Once it's all melted, rinse the inside with soapy water, and thoroughly rinse and dry the inside before turning the unit back on. This can take several hours, but there is a way to speed up the process.

Place a bowl of warm water in the emptied out freezer, and replace it with heated water every 10-20 minutes. This drastically increases the temperature inside and melts the ice far faster, which can allow you to plug the unit back in and replace the food you took out much sooner.
