Paintless Dent Removal Instructions
A hair dryer can help you remove dents from your car. (dryers image by timur1970 from

Do you remember the Professor from "Gilligan's Island"? This classic TV character could make anything from a piece of rope and a coconut. You too can have a "Professor moment" next time you find a dent on your car. All you'll need is a hair dryer and an air duster (the spray bottle product used to dust computer screens and keyboards). With these two household items, you'll be able to remove most dents from your car without having to visit the repair shop or getting a new paint job.

  1. 1

    Set the hair dryer at the highest level. Point it at the dent and apply heat for at least one minute. The heating process will cause the molecules in the metal to move away from each other.

  2. 2

    Grab the bottle of air duster, turn it upside down and spray the dent. Spraying while the bottle is upside down this will cause liquid carbon dioxide to come out. Liquid carbon dioxide is an extremely cold freezing agent--and the reason why you need to wear gloves, goggles and a face mask.

  3. 3

    Let the liquid carbon dioxide remain on the dent for at least one minute. The extreme cold of the liquid will cause the previously heated metal molecules to contract quickly. This will cause the metal to contract and pop up. Use extreme caution when spraying the liquid on your car. It can cause injury if you come into contact with it. Make sure to wear the protective clothing listed above.

  4. 4

    Clean any leftover liquid with a rag or paper towels.

Tips and warnings

  • Do not attempt this without wearing gloves, goggles, long-sleeved shirt and face mask. The air duster will spray out a freezing liquid that can cause severe injury if it comes in contact with your body.
