Easiest way to go is just to have it acid dipped.

Acid dipped in California?
I'd pressure wash all the grease and oil off of it in and out and then sand blast it in and out. Then paint the outside and after it's dry I would pressure wash the inside to remove any sand. Then your ready for assembly and gear oil.
Or look for another housing...

I'm pretty sure the petroleum based hot tanks that repair shops of yesteryear had are banned here. (elsewhere too?)
All the repair shops here have aqueous based hot washing tanks with high pressure sprayers that revolve around the part.
But I think there are special places in California that dip car bodies to remove paint and rust. So I'd think those places would do a rear end housing. Maybe they advertise in Drive Magazine??
I know they acid dip for removal of metal (chemical machining) still here in So Cal. I think it's used in the aircraft industry. Don't know if they would do a project like this though.

Just glass bead or sandblast the interior then wash it out thoroughly with soap and water then blow dry.
I've done it many times and then painted the interior with Rustoleum Red Primer or Glyptol.

I've got a 8.75 house that is all rusty and scaly on the inside. I can wire wheel the outside, but what the easiest way to clean out the inside to get it ready for assembly??? The local machine shop wants $40 to hot tank it. Any ideas????
I would hot tank! 40$ is money well spent. Napa did this manifold and it came out looking like new
That is without ANY follow up bead blasting? Nice!
What sort of cleaning tank did they use to get that?
Can they still do the old fashioned caustic chemical hot dip like the old days in other states??

Are you sure it was tanked? Looks more like cooked and shot beaded.
No a real castic hot tank will make them look like new, even eat the rust off. I used to use one quite a bit.
Most imoportant thing to remember on sb is to grind off the rivets holding the cover on the bottem of a stock intake to get it clean and clean the plate separately in the hot tank.

That is true when I took in the 340 intake they took off the bottom pan hot tanked it and reinstalled it. The unit came out looking just like the big block piece. In Washington they must still be able to use the real deal solution not sure what it is but it works sweet. I have a whole slou of valve covers I need to take in next.

I found a local blasting facility that is sand blasting the inside for $40. Heck of a deal if you ask me!!!
I was told to blast with caution, and not the inside. While blasting will clean the inside there will be little places where media (sand etc) sticks to the grease and you'll have a hard time seeing it or getting it out. Then it was clause issues with your diff down the road.
A solvent tank / Acid Dip process is a better route I think, as the grease is removed and the metal is clean.
If you have the outside blasted only seal up the housing really really well to prevent media from getting inside.

There was no oil or grease on the inside. It was dry as a bone and rusty and scaly. The axle ends really weren't that bad. The axles came out pretty easily as did the axle seals. I'll hit the axle seal and bearing ends with a cylinder hone just to clean them up a bit. It'll be good to go.

Run this though the rear end housing with a pool pump for a few hours... Rust remover
I agree that this and other similar products like Evaporust and Unrust will do a great job, however if he can get it done at a machine shop for $40.00 they are typically going to cost more to get the job done based on the size of the rear end housing and the amount of those products needed to do the job, hence my suggestion to use the home brewed vinigar mix instead.

It's interesting how people like to spend other's money. I'll happily take donations for a new one. But that ain't happening, so the next best is refurbishing this one. Once it's together, there'll be plenty of year of service left in this old housing.
