How to Keep Rubber Trim From Cracking

Rubber trim is used to keep the seal around windows, doors and certain car parts secure. Rubber is great for this medium because of its durability and pliable nature. It can be fit into almost any area that needs sealing. The difficulty with rubber trim is that it can develop cracks from extremes in weather, use and age. Minimizing the wear and taking care of the trim will extend the life of your trim a long time.

  1. Clean your car inside and out to remove any debris that might attach itself to the any areas with rubber trim. This is your first line of defense against cracking.

  2. Keep sunlight from directly hitting as much of the trim as possible. For a car this would mean parking in the shade or a garage.

  3. Avoid extremes of heat and cold as this is the primary reason for cracked trim. Use a car blanket in the very hot or very cold seasons.

  4. Look for products that contain UV protection when looking for cleaning products. They will cost a little more than cleaners without UV protection, but you will save the difference by not having to replace the trim.

  5. Avoid using any product that has silicone as an ingredient as silicone can harm the trim.

  6. Repair small areas as soon as you notice a rip or tear or the smallest crack. Use a rubber replacement patch that matches the trim.

  7. Use appliances such as dishwashers that have rubber trim once a week to avoid the trim drying out and cracking. It is also good for the pipes of such appliances.
