Here is my heater and a MK4 1.8 turbo head after in the cleaner.

I haven't done anything with it. Just don't really have time at work to screw with it I will at some point. I'll look at that I think it was the sonic part of it but it could be the control board. It was lit but nothing seemed to happen. Might have to plug it back in to see.

Based on all the positive feedback here, I bought one of these units recently. I have to say that I have been very disappointed.

I purchased a Kendal Commercial Grade 27 Liter 900 Watts HEATED ULTRASONIC CLEANER HB27 off of Amazon about a month ago. This unit appears to be identical, except for the name, to the ones shown in this posting.

This is the one I purchased

I was pretty excited when the unit arrived based on all the results I had seen for parts cleaned ultrasonically. I had just completed disassembly of a pretty gunky 2.4 liter motor and decided to try the cam towers first. I laid one cam tower in the tray, filled the tank with hot tap water, added a cup of Simple Green, set the heater to 50 deg C, waited until the temp reached 60 deg C and set a 45 min cycle. Lots of noise but after 45 minutes no cleaning at all.

I contacted the domestic rep, New Shining Image (NSI), via email and they suggested they would send me a new circuit board. I insisted I wanted to return the unit and have them send me another one. They finally agreed and off it went back to Middletown, NY. In less than a week, another identical unit arrived and I set it up. This time it did do some cleaning of the cam tower but even after two 45 min cycles at 60 deg C, there was still caked on grease in the crevices of the cam tower. OK, not what I expected but better than slaving over the parts cleaner for 30m min.

I cleaned a few other items, heads tin, small pieces. Nothing came out perfectly clean. Then, after about 10-15 cycles, the transducers quit. No cleaning action and no surface agitation in the tank. The unit still makes the same sounds as when it did do some cleaning.

I contacted NSI again and will be returning the unit for a refund.

I would still like to buy a different ultrasonic cleaner but my experience with this one makes me leary about buying another inexpensive Chinese unit.

I have been running one of these for a couple days, cleaning everything. They are down to roughly $200. The first time I tried it with some dawn and simple green but it wasn't that doing the job then I reread this thread and man.. putting a 1/2 cup of dawn is the trick. That is a lot of soap but it really cleans things up.

Zep from ace hardware is really nice cleaner in the ultrasonic. Maybe too harsh for some things tho. It took the sink playing off a part the other day.

zinc coating?

If so, thank you for the warning. It's good to know what not to use in cleaning parts so we don't damage them.

Ultrasonic cleaning will remove zinc coatings and also anodizing. Be careful with it or watch it like a hawk.

Yes zink. sorry I have fat fingers

Zoe degreaser has a high pH level so on the aklyline range. Is is the opposite of acidic but equally as caustic. It definitely attacks zinc and anodizing.

Purple Power and SG in high concentration can be damaging.

I have had mine for a few years and I'm very happy with my purchase. Although I wish I had gotten a bigger one
