How to Clean Silicone From Cast Resin

Resin is often cast in flexible molds made from silicone rubber. The flexibility of the molds makes them easier to remove than stiff plastic molds once the castings have cured. There can, however, be residue left on the resin from the mold, or resin left behind on the silicone. Applying a small amount of rubbing alcohol to silicone rubber molds makes the silicone extremely slippery, and can be used to clean both the casting and the mold.

Instructions

1. • 1

     Pour a small amount of rubbing alcohol onto a rag, and rub it on the cast resin figure. Rub away any residue from the casting process.

   • 2

     Use a dry, clean paper towel to wipe all rubbing alcohol from the resin casting.

   • 3

     Repeat the process on the mold. To extend the life of the mold, remove castings as soon as they cure and immediately clean the mold. After removing any leftover resin with alcohol, wash with dish soap and water.
