How to Care for Exterior Auto Plastics & Rubber

Rubber seals and plastic trim are common on today's vehicles. Exposure to harsh environments and sunlight cause the moisture held in the materials to dry out. Dried-out rubber and plastic become brittle and crack. The cracks can escalate, causing air leakage around the rubber seals and peeling paint from the brittle plastic. Treating the materials with a cleaner containing a moisturizer will prevent the rubber and plastic of your vehicle from becoming brittle and cracking.

Things You'll Need

  • Car washing liquid
  • Plastic bucket
  • Water
  • Rags
  • Exterior cleaner
  • Clean rags
  • Vinyl and rubber protectant
  • Restoration dye
  • Pour car washing liquid into a plastic bucket. Fill the bucket 3/4 full with water. Wet your vehicle with clean water. Wash your vehicle with a rag soaked in the plastic bucket. Allow your vehicle to dry.

  • Apply exterior cleaner onto the rubber and plastic with a clean rag. Wipe the cleaner from the materials when dried.

  • Pour vinyl and rubber protectant onto a clean rag. Wipe all vinyl and plastic parts of the vehicle with the vinyl protectant. Use a circular motion when applying the protectant to the materials to ensure complete coverage. Allow the protectant to absorb into the materials before wiping it off with a clean dry rag.

  • Wipe restoration dye to black rubber seals with a clean rag to remove discoloration from the material.
