Spray a sufficient amount of Depo-Cleaner onto the dirty area on the die or mold. Let it sit for 3 to 5 minutes so it penetrates. Then, run a few shots while the die or mold surface is wet. There still may be some cleaner remaining, so be sure to use a solvent like the GP cleaner to rinse it. This spray is ideal for die and mold temperatures between 40° and 80°C.
