To clean your silicon molds, wash them after use with soap/dishwashing liquid and warm water. Never use sharp/rough tools or your nails to remove uncured resin stuck on the molds. Doing so will damage the mold. If there is still resin left after washing with soap, you can use tissue soaked with alcohol to wipe off the resin. Once clean, wipe it dry and store flat in a box or container away from heat and dust.
