Refrigerators can become frosty and icy for lots of reasons — whether the door has been left open, you’ve put hot food in to cool, or the door just has a bad seal, annoying frost can build up and begin to smell. It’s no glamorous job, but at some point you may have to defrost your refrigerator. Some methods can take over eight hours, but there are tricks you can use to make the process much faster.

Things You Should Know

  • Empty your refrigerator, unplug it, and leave the door open to defrost for at least 8 hours.
  • Set a pot of boiling water on top of a towel in the fridge to speed up the defrosting process.
  • Use a hair dryer to melt stubborn bits of frost, and/or set up a fan in front of your open refrigerator to really get things moving.

  1. Take this as an opportunity to get rid of all the junk or expired food you’ve collected over time! To stop the rest of your food from spoiling when you remove it from the fridge, store it in coolers or on ice. [1]
  2. Though you don’t necessarily need to clean them all, this would be a great time to do so. Be careful at this point, since cold plastic is more likely to be brittle and break.

  3. [2] Moving the fridge away from the wall will make it easier to clean any leaking water, as well as give you the chance to sweep behind and beneath.
    • At this point, it’s also important to lay down some bowls or towels to collect water that may leak out as the frost melts. [3]
  4. If you’re not in a rush, this is your best option to thoroughly defrost the fridge, though you will need to find a more stable and cool place to store food for this period of time. [4]

Speeding Up the Process

  1. [5] The heat will help to more quickly melt the ice and frost, but be careful! Make sure to put a towel, blanket, or pot holder underneath to protect your floors. [6]
  2. For larger chunks of ice, loosen them first with the dryer, then use a soft, plastic spatula to chip away or pick it up out of the fridge.
    • Only use a hairdryer if your refrigerator does not have styrofoam insulation, which could melt. [7]
    • It’s important to use a plastic, not a metal spatula, because metal may puncture or damage your refrigerator. [8]
  3. The increased airflow will not only help to defrost your refrigerator more quickly by raising the temperature, but it will also help some of the melted water evaporate. This will make clean up much easier! [9]

    I recommend unplugging the refrigerator and letting the ice melt on its own. If you need to speed up the process, you can also use hot water to help the ice melt.

    In many cases, yes! However, check that your freezer doesn't have Styrofoam insulation first. If your freezer has Styrofoam insulation, it may melt if you direct a hair dryer at it.
