I have multipe Trans. and Engines that have years of caked dust/dirt/mud/etc on them.

What is the best way to getting them to look new? Power washing? Parts cleaner?

I know this is such a newb question, but hey! I'm a Newb! (IMG:style_emoticons/default/unsure.gif)

Steam cleaners rock. But not everyone has access to them.
You could take them down to a carwash with the pressure wands, soak everything good with brake cleaner (or see if someone chimes in with a better chemical), let it work a bit, then power wash it off.

I've always used a big shop sink, a ton of degreaser, maybe some brake cleaner, rags, and a wire brush. You can clean off pretty much everything that way, it just takes time.

Though if you want to clean assembled stuff a powerwash isn't too bad an idea. Just make sure you don't do it over any grass.

If I remember correctly, Dr. Evil recommended Easy Off & a power washer for the tranny.

I used a small screwdriver to scrape off the caked mud on my tranny. Looks good enough.

Whatever you use, be careful! I wouldn't steam a tranny unless it was coming apart right away. That Castrol purple cleaner can EASILY put you in the hospital, so use it in a WELL ventilated place with a good breeze blowing. Easy Off can damage the magnesium tranny case and other bits, so be careful there, too. Oh, staem cleaning can permanently discolor aluminum engine cases (OK, anything made of aluminum .............. )

Drench the tranny with degreaser. Use a wire brush to get the caked on dirt off. Rinse the degreaser off with water. Don't do it over grass that you want to live.

Oil Eater, they sell the stuff at Costco, and I like it far better than the simple green and purple power stuff. Works better IMO and less nasty.

Can't you just take it to a machine shop and have them stick it in there parts wash tank? That is if it's disassembled.

I don't think I'd powerwash any motor or tranny that I wasn't going to disassemble.

too much chance for water to get inside
I've power washed cases and things I had apart in the past.

but for a tranny or motor that I'm not taking apart
I usually spread out a big piece of cardboard
and use:
- naphtha (solvent) I put some in a coffee can
- a variety of brushes (tooth brushes, paint brushes, brass bristled brushes)
- a spatula
- an old screw driver

this way I control how much gets onto the tranny
nothing gets inside
I roll the tranny over to get the sides and bottom

it takes time but comes out pretty decent
I wouldn't suggest getting any liquids inside other than grease

Easy Off oven cleaner and a pressure washer are what I have used with low effort and good success. I did an experiment with a tranny case and put Easy Off on it for over a month, kept soaking it, when I finally washed it off it was not damaged. Easy Off is not strong enough to eat your case, that is an urban myth.

I yield to your experience, anecdotal though it may be ..............

Anecdotal?! (IMG:style_emoticons/default/bootyshake.gif)
Def: based on or consisting of reports or observations of usually unscientific observers

My study was scientific. It was only lacking in that I didnt repeat it over and over again. Nor will I as it is pointless. I set the parameters to be obscene in that I soaked the palate for 1 mo. Before one does a study they first see if there is a reaction to study, there was no significant one here. When used for a normal amount of time required for cleaning (less than a month), Easy Off has thus far proven to be non damaging.

For the tranny I remove the vent, and plug with a wheel bolt.
Then I take to the local transmission shop for cleaning.
Upon return I replace the input and output shaft seals.

For the magnesium parts, Mineral Spirits, nylon scrub brush and elbow grease. Simple Green also works well. Dr. Evil may have had good results with the Easy Off, but I personally would be concerned about potential damage to machined surfaces.

Your next question should be "How should I protect the magnesium case once it is clean". My suggestion is CRC brand "Heavy Duty Corrosion Inhibitor". It is a Tectyl like spray on wax coating.
