Best ultrasonic lp cleaner in 2020 and what surfactant best?

I have a Klaudio. In this particular machine, Hepastat 256 is what you want to use at a concentration of no more than 2.5 ml per 2,500 ml water (0.1% concentration). I’d suggest between 1.5 ml and 2 ml, actually. 

I love my Klaudio, but since they are no longer available, if I were to buy new, I’d get a Degritter.
