FWIW, I have had great results using Costco Kirkland brand laundry detergent in my ultrasonic cleaner. Surprisingly, it cuts grease really well and it's very cheap.
Yep. My go-to detergent's the same All Free & Clear I use on my clothes. Proportion's different though, detergent:water; the ultrasonic gets ~ 30ml / liter H2O where the washer gets 30ml to whatever the washer decides it needs for the load I put innit.
Longest cycle on my US's 8 minutes. Really dried crud needs four, five repeats to get decently clean. And I learned early on to put dirty items in a plastic baggy
then into the basket 'cause the gunk that comes off settles to the bottom of the US tray otherwise & later is a major PITA to get rid of.
