How to repair car door dings

Updated February 21, 2017

As sturdy as cars are, it doesn't seem to take much to get a ding in them. Car doors take a lot of abuse, whether it's from a freak hailstorm or a careless person in a car park. These dings can detract from the aesthetics of the vehicle. Fortunately, it is a very simple fix that only takes a few minutes and can save you a lot of money by allowing you to avoid the bodyworks garage all together.

Hold a piece of dry ice in the centre of the dent for several seconds and remove it. Within a minute, the dent should pop out on its own.

Place a small piece of aluminium foil over the ding and heat it with a lighter for 30 seconds. Spray liquid CO2 on the heated area by holding a can of compressed air upside down and spraying it. In 30 seconds to a minute, the dent should pop out on its own. Once the ding is gone, wipe the area with a clean, soft cloth.

Hold a hair dryer to the ding for 20 to 30 seconds until it is hot, and spray with an upside-down can of compressed air, covering the area with liquid CO2. The dent should pop out on its own in less than a minute. Wipe the area clean with a soft, clean cloth.

If the car has been sitting in the sunshine on a hot day, place a cold, wet cloth on the ding; the dent will come out.


Never handle dry ice without gloves.
