This 4 oz. water based solution is non toxic, non flammable, and environmentally safe. It's molecules grab powder residue, grease/lube, gun debris, and any other organic type molecules that don't belong and pulls it away from the area being cleaned. This makes cleaning safe and easy to do. It is safe on wood and plastic too, so there is less worry about overspray. This is the perfect prep step for oiling/greasing the parts that need to be taken care of.
