How to keep rubber from cracking

It's essential to know how to keep rubber from cracking. Why? Because you have rubber all over your home. Learn ways to store and condition your rubber to prevent cracking and drying out. Find out why rubber degrades and how to make it last.

How to Keep Rubber From Cracking

Rubber is prone to degrading and cracking with time. Rubber is a naturally sticky substance that is put through a vulcanizing process to make it hard and smooth. This process makes rubber great for the soles of shoes, rubber coatings on tools, and kitchen wear. To keep your rubber from cracking, it's all about storage and conditioning.

  • Store rubber at room temperature

  • Avoid exposure to UV light

  • Wash rubber with gentle cleaners

  • Keep conditioning to a minimum to restore softness

  • Store rubber objects in airtight containers

Sticky Rubber Syndrome

No matter how diligent you are, rubber will eventually degrade and become sticky. Preservation and conditioning methods can keep the rubber soft, but over time it will break down. When rubber flexes or stretches, there is nothing you can do to restore the rubber. You can patch it, but the rubber molecules' degeneration can't be repaired.

How to Keep Rubber From Drying Out

To prevent the rubber from drying out or to restore the softness to rubber that is getting dry or cracked out, your first thought might be to reach for petroleum-based products, but don't. This can contribute to the degrading of the rubber. Instead, you want to reach for items specifically designed to seal and protect the rubber. Explore commercial and homemade conditioners for keeping your rubber supple.
