The BTSC16OZ from Breakthrough Clean is a high-performance suppressor cleaner. Unlike traditional cleaners, it is water-based and ammonia-free, employing a unique combination of detergents and surfactants. What does that mean for you? It means this cleaner is capable of effortlessly removing heavy deposits of carbon, lead, and copper from your muzzle brake, compensator, suppressor, and flash hider.* To get the best performance, it is recommended to immerse the suppressor in the cleaner for a period ranging from 8 to 24 hours.
