Is there anything more frustrating than a fender bender? Dents and dings in your bumper can really throw off your mood and the look of your car. But have no fear! You can actually remove minor dents without the help of a professional or fancy equipment. All you need is some boiling water and a little bit of elbow grease. To make the job easier, we’ve answered a few common questions about the process.

Question 1

Question 1 of 5:
Does boiling water work on metal and plastic bumpers?

1
Yes, it can help remove dents from both metal and plastic bumpers. Fill a pot with water and bring it to a rolling boil. Carefully pour the water over the surface of the dent to heat up the metal. Allow the metal to flex and return to its original shape.^{[1]

- Don’t press the dent out of metal like you would for a plastic bumper.
- You may not be able to remove all dents from metal bumpers.
2
Pour cold water over the area to help the bumper retain its shape. If the bumper is plastic, keep pressing out the dent from the inside until it’s fully removed. Then, pour a pot full of cold water when you’re finished to solidify the bumper.^{[3]

Question 5

Question 5 of 5:
Can I drive with a damaged bumper?

1
No, a damaged bumper is no longer able to withstand impact. Cracks and dents are more than just cosmetic problems. Even small ones can affect your bumper’s structural integrity. If you get into another accident, even a small fender bender, your bumper won’t be able to absorb the impact and it could lead to damage to your vehicle’s body.^{[8]
