A clean mold is a long-lasting mold that can be used time and time again, for many years to come. Therefore, spending a couple of minutes cleaning your mold after use is really worth it, as it will save you money and effort. Clean your molds immediately after use. Do not allow leftovers of the medium you used (clay, fondant, etc.) to dry on the mold, as they will be difficult to remove later on. Use baby wipes to wipe off any stains, lint, small particles of any kind. For more stubborn stains, use a wipe and rubbing alcohol. You can also use warm water and soap. Use a softened chunk of clay to pick up lint or pieces of clay stuck in hard to reach areas.
