At the far end from the basic kits, you’ll find ultrasonic cleaning systems. The ultrasonic vibrations of the cleaning tank, combined with the proper solvent solutions, does all of the scrubbing for you, producing a squeaky clean gun in a short period of time. Another dip in the tank with the lubricating solution will help to protect the gun from moisture. Although ultrasonic systems are more expensive, they don't have to break your budget. A system like the L&R HCS 200 provides everything you need with a balance of function, tank size and reasonable pricing.
