Cleaning carbon...Ultrasonic?

We are disassembling an engine that has significan carbon. Having run alky for so many years, I haven't seen carbon in forever.

I have heard oven cleaner works wonders, and also ultrasonic cleaners.
Any experience? What budget ultrasonic machine and what fluid in them?

Also, the crank has some rust...not on the bearing surfaces but on the counterweights. How do you go about removing that?

I'm out of my element with "dirty" parts here. LOL.

And....how effective are the big washers at the machine shops? Are these the easy answer to all these questions? Rust too?

For the crank, some thing like this will polish it right up w/o material removal. Those prices seen awfully high, just referencing the item.

Oven cleaner will dissolve aluminum if left on long enough.

On the big wrench's in the service trucks. When they rust up from no use, i use Lime away. spray/wipe. Then a good coat of WD-40/wipe.

Bucky, Just find a shop that has one. It is a 15 minute job. You dunk it in the water and turn it on...all done.
We got a new one at the college I work at...it amazed me how good it works. Owning one can be a lot of maintenance...seals go bad if you don't use it enough...then it is the bearing if you don't get right after the leak.

I haven't run across anyone with one yet. We are rural. I have heard of guys using the harbor freight deal. Soaking in the parts washer isn't touching it. LOL.

Don't mess around with ultrasonic when hi-tec laser is the new wave.

I cleaned countless heads and other parts in my engine building days and still do sometimes.

Glass beads in a bead blaster

Nothing could be worse than a Mack cylinder head after about 500,000 miles from a UPS truck.

Hot tanked first and hot water rinsed. That would not touch any very heavy thick carbon built up in intake ports. I used a hammer and a screwdriver or scraper to bust out as much carbon as possible before the hot tank.

Glass beading won’t cut thru gummy carbon. I scrape as much as possible and use solvents that dissolve carbon again before beading.

Alcohol burning engines leave smeary carbon in the exhaust ports. Solvent gets most of it. Even mineral spirits cuts it if it’s thin.

I glass beaded heads of all kinds. Iron and aluminum and any other part that needed cleaning. I’ve even done carburetors that were in rough shape. Turn the pressure down on parts like that.

I still have a big compressor and a beader cabinet that is the size of a 275 oil tank hinged upper half. Works good but is not fun and is a dirty process unless you have a very good reclaimer/vacuum system..

A Mack 6 had 2 heads.

Pretty big intake ports.

One had more of a dog leg shape and would be so blocked with solid coal like carbon I could barely stick a finger thru it!

Busted out chunks and got filthy doing it

I’m still doing dirty jobs every day

One of my specialties, dirty jobs !

Full strength Oil Eater was the bomb in the ultrasonic for carbon. Worked very well.
