This is a question that we get all the time! There are two different ways to do this.
1. The first recommended way for cleaning sorbothane is to use warm water and mild soap. Rinse the sorbothane thoroughly with a small amount of soap. Be sure not to soak it in water. For drying, let it air dry.
2. You can also clean sorbothane more deeply with using a very small amount of alcohol. Please do not soak. Be sure to air dry using this method as well. Please avoid the use of solvents.
