Using the TriggerFoam Pro Cleaner is easy. For application tools, just spray the cleaner inside and outside the tool to remove the uncured polyurethane foam. If you get foam on your hands or clothing, apply a small amount of the cleaner and gently wipe it off. When using it on other surfaces, first test it on a small, hidden area to make sure it won't cause any damage. Since the cleaner is extremely flammable, always use it in a well - ventilated area. Never smoke or have any open flames nearby. Keep it away from hot objects and things that can create sparks. After use, store the can in a cool, dry place, away from direct sunlight and heat sources.
