  • Question
    If I spray with Pam or oil, will that help the soap not stick to the molds?
    Community Answer
    Yes, this does help with demolding if you're using a solid (not silicone/thin plastic) mold. Just be careful not to spray too much, or you'll find you have to wipe down the soap afterwards, or you might even get an uneven surface in your soap from uneven oil application. Try using something like coconut oil or shea butter if possible.
