Step-by-Step Guide: How to Clean Resin Molds Properly for Reuse
Cleaning resin molds correctly depends on whether the resin inside is cured or uncured. Follow the method below for both scenarios.
✅ 1. Cleaning Resin Molds with Cured Resin Left Inside
Cured resin is solid, making it easier to remove without damaging the mold.
Steps:
-
Gently pull the cured resin away from the walls of the mold.
-
Use your fingertips to remove small bits sticking inside.
-
If tiny pieces remain, use a wooden toothpick (never metal).
-
Wash the mold in warm soapy water.
-
Allow the mold to air dry completely.
✅ 2. Cleaning Resin Molds with Uncured (Sticky) Resin
This is trickier and requires careful handling.
Steps:
-
Wipe away uncured resin with baby wipes or a microfiber cloth.
-
Use isopropyl alcohol to break down the sticky residue.
-
Dab gently—never rub aggressively.
-
Rinse with warm water and mild soap.
-
Let it air dry upside down.
How to Deep Clean Your Resin Molds
Deep cleaning is essential if:
-
Resin has stained the mold
-
The mold looks cloudy
-
It smells from previous pours
-
Glitter or pigments are trapped
Deep Cleaning Steps
-
Fill a bowl with warm soapy water.
-
Soak the mold for 10–15 minutes.
-
Use a soft sponge to massage the interior.
-
Rinse thoroughly.
-
Dry completely before storing.
How to Remove Stains or Cloudiness from Silicone Molds
Silicone molds can become cloudy due to:
-
Micro-scratches
-
Pigment residue
-
Alcohol exposure
-
Oily resin additives
Fix:
-
Apply a thin coat of mineral oil
-
Buff gently
-
Wash again
-
Dry completely
This restores clarity and reduces surface micro-scratches.
