I tend to use small or large rotary devices that I can let run for hours or
days if needs be. If the turnbuckles are small, the little "rock polishers"
from Harbor Freight are good with whatever abrasive/solventive media you
wish in with the parts.

If the turnbuckles are large, a **clean** cement mixer withOUT the internal
stirring paddles and the holes blocked with botch buttons along with the
media work just fine.

The abrasive media of choice here for that sort of crap is "playground sand"
from Home Depot. It is very fine and clean, but you may wish to research
other less invasive media. Pistons and valves come out sparkling clean with
this media but you've got to figure out how to get ALL the remaining sand
off of the part ... generally a solvent soak followed by an air blast
followed by another solvent soak.

I've got a bunch of old turnbuckles that were apparently removed from
planes
eons ago. They're covered with black, cruddy, dirt and grease. What's
the best
way to clean these up?
