A freezer covered with a thick layer of ice can take up valuable storage space and may make the appliance work harder. If frost has built up significantly, it’s a good idea to defrost and clean the freezer.
The good news is that you can speed up the process considerably with a simple method using hot water. However, the popular claim that every freezer can be completely defrosted in exactly five minutes isn’t realistic—how quickly the ice melts depends on its thickness and the freezer model.

What You’ll Need
1–2 large bowls or pans
Hot water
Several towels
A soft sponge or cloth
A plastic scraper, if needed
A cooler or insulated container for frozen food
Step 1: Turn Off the Freezer
Before defrosting, turn the freezer off and disconnect it from the power supply.
Remove all frozen food and place it in a cooler or insulated container to keep it cold while you work. (Product Help | Whirlpool)
Step 2: Protect the Floor
Place several towels around the freezer and inside the bottom area.
As the ice melts, a significant amount of water can accumulate, so keep an extra towel nearby.
If your freezer has a drainage system, follow the instructions in the owner’s manual.
Step 3: Use Hot Water to Speed Things Up
Place a heat-safe bowl or pan filled with hot water inside the freezer and close the door for a few minutes.
The warm steam helps soften the frost and can make it much easier to remove.
For heavy ice buildup, you may need to replace the water with another batch of hot water and repeat the process. Manufacturer guidance from Whirlpool and GE specifically recommends pans of hot water as a way to speed up defrosting. (Product Help | Whirlpool)
Step 4: Remove the Softened Ice
Once the frost begins to loosen, gently remove pieces that come away easily.
A plastic scraper can be used carefully for stubborn frost.
Never force large pieces of ice that are still firmly attached.
Step 5: Clean the Freezer
Once all the ice has melted:
Wipe away the water.
Clean the interior with a soft cloth or sponge.
Use mild cleaning products appropriate for your freezer.
Rinse away any residue.
Dry the interior thoroughly.
Some manufacturers recommend a mild baking-soda-and-water solution for cleaning the interior. (Product Help | Whirlpool)
Step 6: Turn the Freezer Back On
Reconnect the freezer to power and allow it to return to its normal operating temperature before putting the food back inside.
Follow your appliance manufacturer’s instructions for the recommended temperature and restart procedure.
⚠️ Don’t Do These Things
Never Use a Knife
Do not use a knife, screwdriver, ice pick, or other sharp object to break the ice.
You could damage the freezer walls or puncture cooling components, potentially causing expensive damage or creating a safety hazard. (Product Help | Whirlpool)
Don’t Use a Hair Dryer
Using a hair dryer or another electrical appliance around melting water can create an electrical-shock hazard. Whirlpool specifically advises against using hair dryers or heaters to speed up defrosting. (Product Help | Whirlpool)
Don’t Pour Boiling Water Directly Onto the Freezer
Use hot water in a suitable bowl or pan rather than pouring boiling water directly onto the freezer’s interior surfaces.
The goal is to create warm steam that helps loosen the frost gradually.
How Often Should You Defrost a Freezer?
It depends on the type of freezer.
For manual-defrost models, manufacturers commonly recommend defrosting when frost reaches around ¼ inch (6 mm) or according to the appliance’s manual. (Product Help | Whirlpool)
Modern frost-free freezers generally handle frost automatically and shouldn’t require routine manual defrosting.
Why Does Ice Build Up?
Frost forms when warm, moist air enters the freezer.
This can happen when:
The door is opened frequently.
The door is left open too long.
The door seal isn’t closing properly.
Warm food is placed inside.
The freezer is overloaded.
Humidity is high.
Keeping the freezer around 0°F / -18°C, minimizing the time the door stays open, and checking the door seal can help reduce frost buildup. (Whirlpool)
Final Thoughts
If your freezer is heavily covered in ice, don’t reach for a knife or hair dryer. A safer approach is to disconnect the power, remove the food, place a container of hot water inside, and allow the frost to soften before gently removing it.
The process may take longer than five minutes if the ice is thick, but the hot-water method can make defrosting considerably faster and easier. (Product Help | Whirlpool)
