Having any kind of burn hole in your car upholstery can not only be embarrassing, but can also greatly hurt your car's resale value. Unfortunately completely repairing the upholstery can be very inexpensive. To get rid of that burn hole in your car, you can try removing it yourself. With a few household ingredients, the hole can be fixed and barely noticeable. The main ingredient to fix your car: mayonnaise. It will remove the burnt mark without bleaching your upholstery at all.
Scoop our 1 Tbsp of mayonnaise with a spoon. Dab the mayonnaise onto the upholstery in the car where the burn mark is.
Rub the mayonnaise into the burn with your finger. Mayo helps pull up the burn mark. Only allow the mayo to set into the top of the burn, don't let it soak all the way through the burn hole.
Allow the mayo to set into the burn hole for 10 minutes.
Wash off the mayonnaise after 10 minutes with a damp wash cloth. Once the mayo has been washed clean, the black cigarette burn will also be gone, leaving just the hole.
Scrape off some upholstery fibre with a razor from an inconspicuous area in the car.
Dab a small dot of fabric glue directly onto the burn hole in the upholstery. Use the tweezers to carefully (and slowly) place each fibre onto the hole one at a time. Once glued down, the tweezers can be used to adjust the fibres to they are placed perfectly onto the upholstery.
For a larger hole: remove a small piece of fabric from the upholstery. Cut the fabric so it is close to the same size as the hole. Dab the fabric glue to the hole, and place the cut upholstery fabric to the hole using the tweezers. Use the razor to trim any excess fabric.
