This is the same ultrasonic cleaner I just picked up. Granted the instructions say you only need to use water, but I also see where Harbor Freight sells a cleaning powder for this machine. I have the machine now, and if the only difference between this machine and the more expensive units is this one needs some "help" (a stronger solution), I can live with it.I have an inexpensive ultrasonic cleaner, one of these (http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=3305) and I am not all than impressed with it. Once you add powerful cleaning solution then I question how much cleaning value the ultrasonic action is really providing. I still find myself still having to use a cleaning brush to get harder to dislodge crud off of things like chassis. On Wizzard chassis there is a pocket below the brushes that collects brush dust. Sure, I can use a trimmed flux brush to clean it out, but I'd expect the ultrasonic cleaner to do the job for me, and it doesn't, no matter how many repeated cycles I run it through. I still have to clean it after it's been through the ultrasonic cleaner.
You mean I can use it on my teletype machine? How about on the paper tape reader?I've used industrial ultrasonic cleaners that just ran with distilled water to clean (hello Joe, I'm talking antique computer stuff again!) teletype equipment.
