Professional grade ultrasonic cleaner with a 25-minute timer which is much needed for brass cleaning. It's better than the typical 8-minute (480-second) timer. It's equipped with a heater and digital controls. 2.6 Qt or 2.5 L tank capacity. Powerful industrial grade ultrasonic transducer. The ultrasonic cleaner can also be used to clean jewelry, optical glasses, automotive parts, etc. The brass cleaning solution is a super concentrate. Mix with water at 1:20 to 1:40 ratio. 1 Qt bottle can make 5 to 10 gallons of solution. A full size plastic basket is included. It's much easier to use compared to a plastic tray which is typically included in the other listings. Warning: Do not use corrosive solutions including liquid bleach in the stainless tank! It's corrosive towards stainless steel and will create pin holes quickly with an ultrasonic cleaner. Do not use corrosive solvents.
