The lock-n-load Sonic Cleaner 2L (2 Liter) features an 80 Watt ceramic heater that enhances cleaning action and especially helps when cleaning gun parts. Its large two Liter stainless steel tank holds up to three hundred 223 cases or one hundred fifty 308 cases. Combined with one shot Sonic clean solution, the microjet action of the lock-n-load Sonic Cleaner 2L removes carbon residue and other debris from cartridge cases, small gun parts and other small metal equipment and it cleans internal and external surfaces of cartridge cases and primer pockets. The cleaner's 5 to 30 minute timer allows you to choose the appropriate cycle for your application..
