How to Remove Dents From a Car Door

Updated February 21, 2017

A dent in your car door can be an eyesore. While many turn to a bathroom tool for the answer, tackling the dent with a pink rubber plunger in hand, this method may not be the one for you. Small dents can be handled with a lot less effort with the right know-how.

Heat the dented area with a hairdryer for 30 seconds. Move the hairdryer to heat the area evenly.

Set the dryer aside quickly so the area doesn't cool and then spray evenly with the compressed air.

Allow 15 to 30 seconds for the dent to pop out on its own. Repeat if necessary.

Wipe the area clean with a soft clean cloth.

Heat the dented area evenly with a hairdryer for at least 30 seconds.

Hold a piece of dry ice in the centre of the dent for 15 to 20 seconds.

Remove the dry ice and wait for the dent to pop out on its own. This could take up to 30 seconds.

Repeat as needed and wipe the area clean with a soft clean cloth once the dent is gone.


For large dents, contact an auto body specialist. If your car has been sitting out in the sunshine all day and is already warm, you won't need to use the hair dryer.


Wear gloves when handling dry ice.
