ultrasonic cleaning engine parts
 

Dear Friends
i Just bought 360 liter ultrasonic cleaning machine to clean our very contaminated cylinder head and other engine parts, but the result is not like as we see on YouTube videos ,
so i just wondering if those clips are really true, Which part of our work is wrong? since we never seen that kind of cleanness on our automotive parts as we see on advertisement .
its very kind of you if you could help us about our problem ?
our machine specification : 360 liter / 3600 Watt ultrasonic power / 28 khz / bottom mounted transducers / power control - degas mode and automatic loading and unloading .
do you think the problem is our machine or we have to find a better detergent ?
do you use any kind of pre washing method before putting in your ultrasonic ?
how much time approximately do you spend for cleaning very contaminated engine parts on your machine? http://forums.pelicanparts.com/uploa...1519460318.jpg

I used a professional service to clean my carburators with ultrasound and I was quite disappointed with the results. They weren't bad, but some grime was still there and I could wipe it off easily with a towel. I was told it has to do with the shape of the parts, cleaning inside the fuel bowls for example isn't easy because the waves don't get there. But the whole point of cleaning a carb is getting to remote places! So I've given up, I'm currently very intrigued by steam cleaning.

I prefer power washing and spraying with degreaser after using Safety Kleen

I have a 60 gallon machine about 11 years old does not clean like it used to. My shop does Porsche transmissions the gears are cleaner with a safety kleen hot soap and water machine. I think the soaps have changed.

My housings go in the jet wash first. Nothing dirty goes in the ultrasonic. I use it for final cleanup only but no longer removes any final residue. It burns up tinfoil like it should so the generators are working. No longer worth the electricity to run it.

Ultrasonic cleaners made in China........
 

Bruce,

I am back to manual cleaning using same methods as you. Bought two (2) untrasonic cleaners in a span of 3 years and they cost more to fix than purchase a new unit. They work well with my wife’s jewelry but not with my dirty parts. Will next try a stove steamer that I got from my daughter.

I bought a heated ultrasonic cleaning tank a few years ago for cleaning watch parts (my other passion...). It's definitely better when using the heat, and I use a solution specifically for watch parts, but despite this, I'm never bowled-over by the quality of the cleaning. In fact, cleaning some oyster/president style bracelets was a bit rubbish, still grease in the hard-to-get to areas. In the end, I used that warm cleaning solution with a toothbrush and cleaned it manually...defeats the object completely. So no, I'm not a particular fan of U/S cleaners....underwhelming.

I worked with this today.
Good results on my case and cam carriers

What cleaning solution did you use? Was it heated? How long?

It is called H7, it is a degreaser.
Two hours, no heat.
I had to scrub some but good results

I also cleaned the case.

We use a Jet washer and soda blasting for effect. Parts look like new when done.

I have found with my ultrasonic cleaner that greasy stuff does better with pre-clean. If the solution is clean and the parts are not greasy works really well (think old carb that's not greasy) with gas stains). If parts are greasy it seams to not work as well basically turning the grease and water into a homogenized solution (like 2% milk) where the grease is now evenly dissolved in the solution and still all over the part. I also found that more detergent was a good thing. I now save up parts to clean and go from least oily to most.

Thanks for share info in this threads :confused::confused:

Are you looking for engine parts? We have cylinder, cylinder head, fuel filter, air filter, oil filter, piston, piston ring, injector, turbocharger, fuel pump, diesel generator, alternator, etc.

I was very disappointed with the two different ultrasonic cleaners I purchased on EBay. My best home-shop cleaning & degreasing method is to soak parts on Berrymans for 24 hours and then high pressure water blast. Any residual baked-on dirt is removed with soda or bead blasting.

Same here. Also a diesel powered steam high pressure power washer. It blasts the tar and baked on grease out of all the nooks and crannies. Also an commercial ultrasonic cleaner and a vapor blaster. It just depends what you need done.

I bought a $4000 ultrasonic tank and tried 3 or 4 solvents. The best solvent came from Bob at Anchor Atlantic. The results were pretty darn good. You need to heat to at least 160 f for best results

The trick is soda blasting. Ultrasonic just doesn't give that "like new" look. Soda is harmless to the motor and even if there is some small amount left in the crevices it just dissolves. Only way to really remove tough grime.
