How to Clean Resin Molds?

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

Cleaning Molds Before Usage

Starting your resin project with clean molds is mandatory, even when buying new molds; cleaning them before using gets you rid of dust and unwanted particles so you always produce a high quality finish piece. 

Let's see how you clean silicone molds before using them:

 Use a soft brush

Silicone molds in general can be easily cleaned with a soft brush or a make up brush, a tool that is available at your home at all times (make sure it's a clean brush).

Use warm soapy water

When starting a new resin project, make sure that the resin molds are clean. If you already cleaned them before and want to use them again, it is best to clean them once more; because the molds may look clean but there might be unseen dust to the eye. Warm soapy water makes the silicone molds surface smooth, flexible which enables you to remove any previous stuck resin to the mold and prevents dust from gathering on the mold. *Don't use hot water, only warm water.

Use tape

Clean the mold with the sticky side of the tape and it will get rid of any dust, mica, glitter. Fast and easy and also easily available everywhere.

We suggest you to put the silicone mold in a freezer, a few hours will help the uncured resin pop out easily.
