Whether you can remove the dent in your stainless steel refrigerator depends largely on the dent's size and severity. Large dents, with sharp, well-defined edges, can be very difficult to remove and may require expert help. Small dents, especially rounder ones, can often be repaired in just a few minutes.
Wipe the dent with a damp cloth to clean it.
Hold a can of compressed air (the kind used to clean computer keyboards) upside-down and spray the contents onto the dent. The propellant in the can should freeze the dent. Freeze the dent as thoroughly as possible.
Heat the frozen dent immediately with a hand-held hair dryer. Hold the hot air directly on the frozen dent until the metal expands and "pop" back out.
Repeat steps 2 and 3 one time if necessary. If the dent fails to pop out after the second attempt, it probably will require professional help.
Do not touch the frozen metal with your bare skin Do not spray the contents of the compressed air can on bare skin
