How to clean silicone molds

After finishing any amazing epoxy resin project, all you have left is an amazing piece of resin but a dirty and sticky silicone mold. And no matter how you try to keep resin molds clean either from resin or dust, they are always dirty.

Cleaning resin molds is cost-effective and can extend their lifespan.

How to clean silicone molds?

There are a few effective methods you can use to clean silicone molds in general, and you can use these methods as many times as you want before and after working with epoxy.

Cleaning molds before use

Starting your resin project with clean molds is mandatory, even when buying new molds; clean them before use to get rid of dust and unwanted particles so you can always produce a high-quality finished art piece. 

Let's see how silicone molds are cleaned before use

 Using a clean and soft brush

Silicone molds can generally be easily cleaned using a soft brush or makeup brush, which is a tool available in your home at all times (make sure it is a clean brush).

Warm water

When starting a new resin piece, make sure the resin molds are clean. If you have already cleaned them before and want to use them again, it is best to clean them again; because the molds may look clean but there may be dust invisible to the eye. Warm water and soap make the surface of silicone molds smooth and flexible, allowing you to remove any previously stuck resin in the mold and prevent dust from accumulating on the Mold.       
* Do not use hot water, only warm water.

Using adhesive

Clean the Mold on the sticky side with tape and it will remove any dust, mica, or glitter. Quick, easy, and readily available everywhere.

How to clean molds from uncured (sticky) resin

Have you ever made a piece of resin but forgot to follow the proper instructions and ended up with resin that is not fully cured? Don't worry, we suggest you follow the methods below to get rid of this problem

Freezing the Mold

We suggest you put the silicone mold in the freezer; a few hours will help the uncured resin come out easily. Make sure to wrap the silicone mold in a separate sealed plastic bag to prevent it from contaminating food in the freezer. When removing large pieces, use the previous methods to get rid of the rest.

Pros ✔️
