1. Avoid Scrubbing with Soap and Water: Many online resources recommend cleaning molds with soap and water or soft sponges. While this advice is accurate for food-grade silicone molds, it is detrimental for molds intended for epoxy resin. Abrasive cleaning methods can scratch the mold surface, remove the protective oily layer, and potentially cause damage, reducing the shine and lifespan of your molds.

2. No Direct Touching: Avoid touching the mold's inner surface with your fingers or any tools except when pouring the epoxy resin. These can leave marks, diminishing the mold's shine and overall quality, especially for handmade molds.

3. Avoid Unprotected Stacking: Stacking molds directly on top of each other can damage their surfaces. The underside of the upper molds may leave prints or dust on the molds beneath, compromising their clarity and smoothness.

1. Proper Storage: It's crucial to store your molds away from dust and other environmental pollutants that could damage them. An effective practice is to use cardboard layers to separate them when stacking, offering protection against prints and dust.

2. Gentle Cleaning with Scotch Tape: For epoxy resin molds, choose non-abrasive cleaning methods. Utilize a strip of Scotch tape to remove dust, resin leftovers, or lint from the mold's surface. This method is gentle yet effective, ensuring your mold's surface remains intact.

3. Timely Demolding: Don't leave the epoxy resin in the mold longer than necessary. Once fully cured, promptly remove it to prevent potential strain or damage to the mold.

4. Regular Inspection: Inspect your molds regularly for any signs of wear and tear. Small cracks or rough spots can impact the finished look of your resin pieces. It’s better to replace a worn-out mold than to risk the quality of your resin art.
