Silicone turns sticky when fat residues penetrate the pores or when the mold is exposed to detergents that degrade the material. Proper cleaning and drying restore flexibility and prevent surface buildup, extending the mold’s lifespan and keeping textures clean.
Over time, silicone absorbs natural fats from creams, oils, and chocolate, causing:
Sticky or tacky surface
Slight oily smell
This is normal and reversible.
How to restore the mold:
Wash with hot water + mild soap.
Bake the empty mold for 20 minutes at 150°C (professional reconditioning).
Avoid abrasive sponges and harsh chemicals.
Let molds air-dry completely to avoid bacterial buildup.
Premium silicone (like Zealous-grade) is more resistant, but proper maintenance is still essential.
