[sdiy] Ultrasonic cleaner advice

[Andy Lambert]

I've had good results using the industrial version of Simple Green that is
produced without the green dye. They brand it Simple Green Crystal. I use a
medium strength dilution with distilled water. A little bit of work with
IPA and an acid brush before running the cleaner gives good results. I
usually do about 60C for the bath temp and it only takes 5-10 minutes with
the ultrasonic on.
