How to Clean Silicone Moulds After Using E-30 Resin

Clean Your Silicone Moulds Thoroughly After Each Use

Proper cleaning is essential to keep your silicone moulds in excellent condition for E-30 resin projects. A clean mould ensures your finished pieces are flawless and prolongs the mould’s lifespan for future crafts.

Why Cleaning Matters for Resin Moulds

Resin residues left in silicone moulds can cause unwanted marks or cloudiness in your next pour. Regular and thorough cleaning removes leftover resin and additives, resulting in clear, professional results every time. Moreover, clean moulds help prevent premature wear and maintain their flexibility and non-stick properties for repeated use.

How to Clean Silicone Moulds After Each Use

Wait until the leftover resin is fully cured before demoulding, as premature removal can damage both the mould and your project.
After demoulding, gently peel away any cured bits of resin using your fingers—avoid sharp objects, which can scratch or tear silicone.
Wash the mould with warm, soapy water and a soft cloth or sponge. Ensure you rinse away any soap residue thoroughly before the next use.
Let the mould air dry completely, ideally in a dust-free space. Once dry, store it flat and out of direct sunlight to avoid deformation.

For flexible, reusable options like the Silicone Circle Mould, proper cleaning and storage are particularly important to maintain shape and durability.

When Thorough Cleaning Is Especially Important

If you are casting coloured resins, embedding flowers, or using glitters and pigments, leftover particles can easily contaminate your next creation. Clean your moulds thoroughly between projects to preserve the clarity and detail of each new casting.
