Simple Green ratio for ultra-sonic cleaning

[tom tutwiler]

What ratio are folks using with their ultrasonic cleaners? My PH arrived and it needs to have a boatload of crud removed from the receiver. Appreciate all the help in advance. Regards, Tom

It will depend upon how much oily crud you have to break down. The more crud the detergent has to break down, the more SG you'll need. On small jobs I just put a good spray in and watch. If it quits working I spray in more.
