Leave a Bowl of Hot Water In the Freezer

Did you want to speed up the defrosting after you unplugged? If you can, put a bowl of boiling water inside the freezer and then close it.

The steam from the boiling water will help loosen and melt the ice much faster. The water should be replaced three times with 10 minutes intervals in between.

The risk of damage to the appliance is mitigated by this method.

You should not forget to put a wet towel in the area where you will place the bowl of hot water. This will be used as a cushion to keep the plastic construction from wrinkling.

Scrape the Ice

If you don’t have enough patience and want things done quickly, scraper the ice from the interior walls.

While wearing protective gloves, place the ice in a bucket and use an ice scraper, wooden spoon, or spatula to remove it.

Since you can’t keep the hair dryer working the whole time, you need to take breaks in between to prevent the hair dryer from overheating.

If your locality has a hot climate, you may use an electric fan in place of the hairdryer to circulate warm air in the chest freezer.

You can wait for the ice to melt by setting a fan in front of the freezer. This method is more efficient than the first method.

Wipe the Freezer with a Hot Towel

If you don’t have a hairdryer and you’re not living in a warm place, you can use a hot towel for defrosting.

Remove the towel from the warm water with the tong by soaking it in the warm water for a minute.

Before you start wiping the chunk of ice, place the towel in the freezer and wait for the warmth to diminish. Once the ice has fully melted, do this process again and again.
