How to Clean Resin Molds
Figuring out how to clean resin molds is one of a new artists’ most common challenges. Luckily, there are effective ways for you to clean resin molds. Let’s take a look at each method!

However, you must cover these molds in separate bags to keep your food and other eatables safe. After cleaning off the larger resin chunks, you’ll need to clean out the smaller particles with sticky tape.

The wet wipes are easy to use; all you need to do is use the wet wipes on the resin mold until it’s clean. It’s essential to clean it thoroughly, including the corners, to ensure you don’t have any trouble the next time you use your mold.
Acetone comes with its fair share of advantages and disadvantages. However, with the help of acetone, you can clean your molds efficiently and effectively.
But the major problem is that it is not as readily available as other cleaning products. In addition, acetone is also a toxic chemical, so you must take various protective measures before using it.
To use acetone, you will need to wear a pair of protective gloves so you can soak your cloth without your skin coming into contact with it. The solvent will quickly break down the resin residue allowing you to clean your mold effectively.
Warm and Soapy Water
Washing your mold with a sponge and soap-induced water will help you remove the resin from your mold. To effectively remove resin from your mold, you’ll need a toothbrush, sponge, and steel wool.

Steps to Remove Uncured Resin from Silicone Molds
Here are a few steps that you can take to get rid of the uncured resin:
- Pour the Uncured Resin Out
If the resin is still in a liquid form, you need to pour it out of the mold and into a plastic container. But if it isn’t in a liquid form, you can use utensils, like a spoon to scoop the cured resin out.
Make sure you dispose of the resin correctly.
- Take New Resin and Add to Mold

Common Silicone Mold Mistakes to Avoid
Here are a few common mistakes that artists make with their silicone molds:
Not Storing the Mold in a Single Layer
Keeping the mold in a single layer is essential since piling layers can cause your mold to bend and buckle, making it impossible to restore it to its original position. So make sure to have only one layer of resin on your mold at a time.
Leaving Silicone Molds in the Sun and Heat
Keeping the mold in a cool, dry place and away from the sun is essential. Continuous exposure to sun and UV light will make the silicone crumble and stick to the resin.
Not Planning for Long-Term Storage
Sometimes, after inadequate care and precautions, you will notice that your molds don’t stay in shape. One of the ways you can avoid this is by placing a casting on it to keep it in shape.
Making Holes in Your Mold
Your molds can often stretch and go out of shape. Making holes in the mold is not viable since resin can quickly run through it.
You must avoid making holes in your mold to prevent this.
Not Washing Your Molds
Most molds get ruined because they don’t get washed after use. Therefore, you must clean it (with water and mild soap) to save it.
After washing it, you must ensure that it is completely dry before storing it in a cool and dry place.
Too Much Heat
Many resin craft artists use heat guns to speed up their curing process. Therefore, you will need a compact heat gun instead of using flames or a lighter to apply the heat.
