Caring for your molds:
Prolonged exposure to temperatures exceeding approximately 180º F may irreversibly deform the molds. Prolonged exposure to direct sunlight may induce stress cracking. 
LDPE may be susceptible to stress cracking when exposed to ultraviolet light and some chemicals. Wetting agents such as detergents may accelerate stress cracking.

For best results, we recommend hand washing our molds using normal dish washing detergents, avoiding abrasive type scouring pads. LDPE can be susceptible to scratching which may complicate unmolding.
