How to Condition a Car's Weather Stripping

There is nothing like taking a drive in a nice car. The comfortable seating and the quality of the ride is relaxing and soothing. You can forget the day's troubles with a leisurely drive through the country. However, if your weather stripping is dry and cracked it can turn that nice quiet ride into a nerve racking and frustrating endurance test. Wind noise and whistling accompanied by water leaks in the rain and car wash could have been prevented with a little conditioning.

Things You'll Need

  • Bucket
  • Water
  • Mild soap
  • Soft sponge
  • Silicone spray
  • Clean towel
  • Wash the weather stripping. Open the vehicle's doors and wash the weather stripping with a bucket of water and soap. Use a soft sponge to apply the soapy water and gently scrub the weather stripping to remove all dirt and contaminates.

  • Rinse the weather stripping. Using plenty of fresh water, remove the soap by wiping the weather stripping with a water-saturated clean towel. Allow to dry thoroughly.

  • Condition the weather stripping. Spray a clean towel with a silicone spray and wipe the weather stripping. Allow the silicone to absorb into the weather stripping and repeat the process. Be sure to cover the entire surface of the weather stripping with a generous amount of silicone.
