Cleaning up my spare engine that I got with my RD350. There so much dirt, oil, grease, and grime all over the engine. I've used degreasers, dawn soap, simple green, purple power (conservatively). Usually what works best for me is WD-40, it lifts the stuff right off but of course you need to degrease the engine post clean up.
Just curious if there are any other suggestions that others have used to clean up a dirty old engine. :umm:
Brake cleaner. Kerosene.
Just plain old gasoline. Yes I know, dangerous, but works great. Put some in a heavy duty spray bottle and douse it down good. Use a solvent parts wash brush to loosen stuff up and just keep spraying it down. It will come clean.
Vapor blasting is the way to go

^^^^^^^I agree, that is very nice, but I was assuming he is talking about cleaning up an engine that has not been taken apart.
wd for cleanup after scraping, then brake clean does a nice job as well. then i respray with wd.

precisely.
What about baking soda in an air blaster? Safe for internal case cleaning of rust and sludge?

Again, as i said before, I think he's doing this to an engine that's still assembled.
It's all good. I just wanted some suggestion for myself and others who discovering some barn finds that have been sitting for years.
What about the outside, then? Does baking soda blast work we'll?
I used to have an old diesel fired Malmesbury steam cleaner. "Puff the Magic Dragon". That thing would remove everything but metal. It was kind of scary though.
I have used crushed coral in a blaster. Came from an aquarium store. Somewhere in between industrial soda and glass/sand. My friend who owns a Porsche shop swears by fire extinguisher soda for final finishing aluminum. It is slower than other media but ground really fine. Otherwise Harbor Freight has blasting soda. It's a little coarser than baking soda.
Vapor blasting seems to be the new best way. At least it leaves a smoother surface than dry blasting.
