At the end of the day, or each casting cycle, we recommend rinsing your silicone molds with warm water to remove any excess soap formula. Rinsing or washing the soap cavities will not hurt or diminish the artwork in each cavity. Common Sense says, "Do not use abrasives, rigid plastic, steel, copper scrubbers or machine wash".
Let the cavities either air dry (recommended) or wipe with a lint-free cloth.
To store your molds, we suggest stacking the molds up-side down on a board to avoid dirt or debris from getting inside the clean molds.
Soap makers also store their silicone molds, in either a large transparent plastic bag or storage container with a lid.
Follow these steps, and your silicone molds 'Made by Masterline' will last forever.
