How to clean silicone molds?

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

Cleaning the molds before use

"Starting your resin project with clean molds is essential, even when purchasing new molds; clean them before use to remove dust and unwanted particles so you can always produce a high-quality finished piece." 

Let's see how silicone molds are cleaned before use.

 Using a clean and soft brush

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

warm water

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

Use adhesive

"Clean the mold with the sticky side of the tape and it will get rid of 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 the resin not fully cured? Don't worry, we suggest you follow the methods below to get rid of this problem."

Freeze the mold

"We suggest placing 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."
