Refrigerators are one of the most expensive appliances found in the average household, and unfortunately, they are also one of the most likely to be dented. Many kitchens are laid out so that just opening the doors will cause an indentation. Add to that the amount of traffic that most kitchens get, and it's no wonder that many refrigerators are covered in small dents. Before you spend money replacing your refrigerator doors, try a simple trick commonly used to remove small car dents. It will not damage your refrigerator's finish, and takes less than five minutes.
Plug in your hairdryer to an outlet so that it will reach the dent in the refrigerator. With the hairdryer set on high, direct the hairdryer at the dent, with approximately 2 inches between the hairdryer and the dent. Heat the dent for one minute.
Wearing heavy gloves and holding the air duster upside down, spray the dent until it is completely covered with liquid CO2.
Wait one minute. Wipe off the CO2 with a clean cloth.
If the dent remains, repeat the treatment until it disappears.
Once the dent is gone, clean the area with a multipurpose cleaner, or a stainless steel cleaner if you have a stainless steel refrigerator.
You must hold the air duster upside down in order for it to spray liquid CO2.
Liquid CO2 is extremely cold. Always wear heavy gloves when removing dents in this manner.
