I've had both the small 3.7L and the larger 13L unit and they both worked well for cleaning brass. However the smaller unit developed some pin holes and started to leak after several months, I suspect there was some impurities in the steel that the cleaning solution eventually ate through. I'm going to strip the guts from it and make a barrel length stainless bath to attach it to for cleaning barrels obviously. Brass is good at absorbing ultrasonic energy so don't try to do too much at once, just run smaller batches. Since getting the Frankford Arsenal wet tumbler I wont be going back to ultrasonic purely because it does a better job and can hold more brass. I used to dry the brass in a Pizza oven at 60c for an hour but that tended to discolour the brass so now after wet tumbling I rinse in hot water then towel dry the outsides before placing in a food dehydrator for an hour. Results are outstanding with cases looking better then new inside and out.
How's my posting?
