There is a whole debate as to use ultrasonic cleaning for firearm applications or not. To the misinformed, ultrasonic cleaning can be viewed as dangerous to the parts and finishes of guns which could in effect ruin the physical appearance of the gun. Despite the controversy, ultrasonic cleaning is a safe, effective, and more productive way of microscopically cleaning your firearms.

With every process there is a way to do it and a way to overdo it. By using ultrasonic cleaning you have to understand that the longer the firearm stays in the tank does not mean the cleaner it will get. To a beginner this would be the typical mentality, however ultrasonic cleaning of a firearm should not last more than 10 minutes completely submerged in an ultrasonic bath. People who think ultrasonic cleaning is harmful to their guns do not understand the process and simply have been fooled by amateurs in the market that leave their weapons submerged in an ultrasonic bath for a very long and unreasonable amount of time thinking their weapons will be cleaner. In fact the majority of the cleaning is done within the first 5 minutes of placing the weapons in the tank. The U.S Military has been trusting our affiliate GunCleaners.com to clean their guns for life-endangering operations which require the gun to be in top-notch working/firing condition, do you trust us?
