How to Clean and Prepare Silicone Moulds for Resin Pouring

Silicone moulds are the go-to choice for epoxy resin projects thanks to their flexibility and easy demoulding. For repeat use and flawless results, a simple but proper cleaning routine is key, both before and after pouring resin.

Effective Cleaning Steps

After each use, gently wash your silicone mould with mild soap and warm water. Avoid using harsh chemicals, abrasive pads, or vigorous scrubbing as these can harm the surface or reduce its non-stick properties. Dry the mould completely with a soft, lint-free cloth or allow it to air dry in a dust-free area to prevent debris from sticking.

Preparation Before Pouring Resin

Before starting a new resin project, ensure your mould is spotlessly clean and fully dry. Even tiny traces of previous resin or moisture can affect your next cast. Some crafters choose to use a light mould release spray for complex shapes, though quality silicone moulds like the Silicone Hexagons Mould are designed to be non-stick and usually don’t require additional preparation.

When Careful Cleaning Matters Most

When making multiple pours in succession, a quick gentle rinse reduces risks of colour or resin residue transfer.
If working with fine details, any dust or old resin remnants can appear in your finished piece.
For long service life, avoid aggressive cleaning products that could erode or warp your mould shape.
