Why Cleaning Matters

Regular cleaning of epoxy resin molds is vital for their longevity. Neglecting to clean them leads to residue build-up, which affects the quality of your future projects. Worse still, dirty molds are more likely to crack or degrade over time, reducing their performance and lifespan.

Signs Your Molds Need Cleaning

Look out for these indicators that your molds need cleaning:
  • Sticky surfaces
  • Discolouration
  • Foul odours
If you notice any of these signs, it’s high time for a clean-up.

Supplies You’ll Need

Here are some of the cleaning agents and tools you may need:
  • Warm soapy water
  • Alcohol or specialised mold cleaners
  • Soft-bristle brushes
  • Rubber gloves
  • Cloths or baby wipes

Safety First

Safety should always come first. Always wear gloves to protect your skin and goggles for your eyes. Work in well-ventilated areas, preferably outdoors, to dissipate any fumes or odours.

Pre-Cleaning Steps

Before diving into the cleaning, inspect the molds for any damage. Carefully remove any remaining dry resin from the mold, taking care not to scrape or damage the surface.

Step-by-Step Cleaning Process

Follow these steps for a thorough clean:
  1. Soak the Mold: Place the mold in a basin filled with warm soapy water. Allow it to soak for at least 30 minutes.
  2. Scrubbing: Gently scrub the mold using a soft-bristle brush. For hard-to-reach areas, consider using a toothbrush.
  3. Wipe: Use a cloth or baby wipes to remove any stubborn residue.
Remember, the cleaner the mold, the better your next project will turn out.

Rinsing and Drying

Rinse off the soap or cleaning agent thoroughly. Any remaining soap can affect your next resin pour. After rinsing, let the mold air dry or pat it down with a cloth to prevent water spots or damage.

Storing Your Molds

Once clean, store your molds in a cool, dust-free environment. You can wrap them in protective wraps or place them in dedicated storage containers to prevent dust and other particles from settling on them.

What Not To Do

Avoid these common mistakes:
  • Using abrasive cleaners or scrubbers
  • Putting the mold in the freezer to speed up the drying process
  • Neglecting safety measures
