When a piece of tape becomes full of debris, simply get a new piece. You can use sticky tacky putty in place of tape if you prefer. Just break off a piece of putty and form it into a ball to warm it up. Then, press and dab it into the mold. Continue to fold and work the putty to get a clean side when it gets dirty.

For stubborn, sticky resin caught in your mold, let it soak in the soapy water for several minutes. If you’re using a double sided sponge, make sure to only use the soft side. A coarse, scrubby sponge can scratch and damage your mold.

Do not use any heat to dry off your mold, either. Heat from a hair dryer or even the sun can cause your mold to warp and lose its shape.

If you have large pieces of resin in your mold, you can just press the back of the mold to pop the hardened resin out of it.

Alternatively, wet a dry, lint-free wipe with water to scrape away uncured resin.

Once you’re finished, rinse away the resin and acetone with warm, soapy water. {“smallUrl”:“https://www. wikihow. com/images/thumb/f/ff/Clean-Resin-Molds-Step-6Bullet1. jpg/v4-460px-Clean-Resin-Molds-Step-6Bullet1. jpg”,“bigUrl”:"/images/thumb/f/ff/Clean-Resin-Molds-Step-6Bullet1. jpg/v4-728px-Clean-Resin-Molds-Step-6Bullet1. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">
