← Back to How to clean uncured epoxy spots from the surface

Keeping reusable moulds clean is crucial for flawless resin results and to prolong the life of your tools. The right product makes routine cleaning easier, and ensures even stubborn uncured epoxy spots are dealt with effectively.

Which Cleaners Work Best for Moulds?

If you want to keep your moulds spotless and residue-free, isopropyl alcohol and a technical degreaser are the most reliable solutions. For day-to-day cleaning and the safe removal of uncured or tacky epoxy, isopropyl alcohol is ideal, thanks to its quick evaporation and effectiveness on fresh resin.

When cleaning more persistent build-up, or when your mould is made from especially sensitive material, switch to a natural product such as the Strong Technical Degreaser. This formula tackles leftover grease or resin residue without harming the mould surface.

Removing Uncured Epoxy Spots from Moulds and Tools

Epoxy spots that remain sticky or soft require gentle but effective treatment. The best approach is to wipe the mould with isopropyl alcohol using a lint-free cloth. For milder, regular cleaning routines, a natural degreaser offers a safe and gentle alternative, especially for sensitive moulds or when you want to avoid stronger solvents.

Isopropyl Alcohol: Moisten a cloth and firmly wipe away uncured spots. Allow to air dry thoroughly before using the mould again.
Technical Degreaser: Apply directly to the affected area, gently massage, then wipe and rinse. Repeat if spots persist.
For Hardened or Stubborn Residue: Carefully use a Heavy Duty Scraper to lift hardened bits, taking care not to damage delicate moulds.

Always ensure your workspace is well-ventilated and wear gloves to protect your skin from cleaning agents.

Why Mould Cleaning Matters Most

Thorough cleaning is especially important if you reuse silicone or plastic moulds often, encounter uncured spots, or see cloudiness and residue that could spoil your castings. Regular care extends your mould’s lifespan and supports consistent, high-quality results in your resin crafts.
