If you have any difficulties, place the soap molds in your freezer for about an hour. To clean mold, soak in warm water for a half hour or so. Hot water, including dishwasher water, may warp the plastic. Customers who purchased Wave 1 Soap Molds also purchased soap fragrance oils, soap colors, soap loaf molds, and sheer organza bags.
