How to Fix the Discoloration on Jeep Fender Flares


The Jeep Wrangler is a popular vehicle, with 74 different models having been produced since the first Jeeps were produced in 1941. Modern Jeeps have fender flare on all four corners of the Jeep. From the factory, these flares are black plastic, but over time they may fade, losing some of their pigment mostly due to sun exposure. To restore the fender flares to the factory look, it is necessary to clean and condition them.

Things You'll Need

  • Car wash soap
  • Bucket
  • Car wash sponge or rag
  • 3 clean, lint-free rags
  • Vinyl, plastic, rubber cleaner
  • Vinyl, plastic, rubber conditioner

Fender Flare Renewal

  • Fill the bucket with lukewarm water, vehicle soap and a sponge. With the sponge, carefully remove any dirt, tar, or debris from the fender flare.

  • Apply the rubber, plastic and vinyl cleaner thoroughly and liberally, being sure to get the cleaner into all crevices.

  • Buff the plastic, vinyl and rubber cleaner after allowing the cleaner to dry. Use a lint-free rag. Buffing the surface again will eliminate streaks. Repeat this process if there is excessive dirt, road debris or discoloration, being sure to allow the surface to dry before continuing.

  • Condition the fender flares after the thorough cleansing, following the same process as cleaning, being sure to use a clean rag. This can extend the life of the fender flare as well as enhance the factory black of the fender flare.

  • Buff the conditioner more thoroughly and more vigorously than you did the cleaner to ensure complete coverage of the fender flare.

Tips & Warnings

  • Conditioners such as Mother's Back-To-Black or Forever Black are products that work extremely well on vinyl, plastic or rubber, such as fender flares, and do not leave extreme side effects.
  • Specific cleansers will extend the color and life of fender flares.
  • Regular upkeep with the conditioner will help the fender flares maintain a long life.
  • Using harsh chemicals can damage the finish or the entire fender flare.
  • Deep scratches may occur if clean rags or sponges are not used.
  • Leaving the conditioner on for more than 5 to 7 minutes can cause streaking
  • Leaning on the fender flare can pull it away from the vehicle, while pulling on it may cause it to crack.
