You can take it to a shop to have it sonic cleaned. It will get all the carbon and everything off all the nooks and crannys that you cant get to normaly.

soak in kerosene or diesel. after a day or two, get a fine grit wet sandpaper and have at it. for the seal grooves, i usually use an old side seal.

In the shop, we do the first stage of cleaning in a hot water parts cleaner. For the DIYer at home, you can get a used dishwasher and basically have the same thing in your garage. For the rotor faces, we then take it to a bench wire wheel, taking care with the orientation so the wires don't catch the apex seal groove edges. For the side seals, nothing beats an old sideseal as a scraper. For the apex seals, we ground off the teeth of an old file the perfect width of the groove and sharpened the end, so you can push it through the groove and scrape off the carbon in the bottom. For corner seals, we found a little tiny brass wire bit for a dremmel that we chuck into a die grinder. Lots of other little tricks, but those are the main things. Hot water is great for initial cleaning, though. Just don't use your regular home dishwasher; get one on Craigslist or something and keep it in the garage.

this sounds interesting. are you saying that you don't use any solvents or spirits? how clean does hot water get them?

Soak them in undiluted Purple Power (available at Adavnced, Autozone, Wal Mart) for two days. 99% of the carbon comes off without scrubbing. Use a soft bristle brush to get the remnants out of the oil seal groove. Use rubber gloves when dealing with this stuff. It will give you a chemical peel in short order.

I've done the kerosene, wire wheel, other degreaser, etc. Purple Power has proven to be by far the best and easiest to use. It's also a great cleaner in general. I dilute it 50/50 with water for final parts cleanup before assembly.

There is a little soap in the water, but otherwise it is just really hot water. Think steam cleaning. The temp is a bit under boiling, contained and circulated. When you open the door, you have to stand back not to get burned by the steam pouring out. The results are impressive. We use it because it does the work of two employees, does a better job and is environmentally safe (big benefit in these regulated days).

Anyone ever have them acid tanked?

Is there any reason why this wouldn't work on the non aluminum/non bearing surface containing parts.

I live 20 miles across the border, an have heard from a few friends, that engine shops which use "engine acid" will do a handfull of parts for 20 dollars or so.
