cleaning muncie case
 

hello, FNG here, wondering what you guys do to get Muncie cases clean and looking like new? I hate glass beading them

thanks

Vapor blast, lots of motor cycle resto shops have this system.

1) Shot Blasting in Wheelabrator or Vulcan

Very Fine Shot for 5 minutes

OR

2) Run in Shaker Machine with Aluminum "Star" Media

THANKS ALL, I am searching for local vapor blasting, I was wondering if there was some type of acid you could spray on and rinse off?

I am thinking i used oven cleaner and a brush

Paint stripper and a brush, followed by oven cleaner and a brush. That is if it's not terminally tarnished.

plastic media or dry ice blasting.

I have done about 50 cases like this one and they all turn out very nice. They don't finger print and oil wipes right off. Might be a bit different than Oem new but customers always appreciate them.

that's with vapor blasting?

No, it is a good solvent bath, then hot water washer, then a high quality fine glass bead in a Clemco blaster and finally a airless steel shot tumbler. I have ran them through the ceramic scrubber after the shot peen but the difference is minimal for the extra process and labor cost.

If blasting isn't an option I went this route with an old distributor for another project and it turned out ok. Other pieces of the distributor I used other forums of cleaning as well as chemicals but for this discussion I'm referring to just the distributor housing.

Powerclean or degreaser with hot water. Then use Black Magic Aluminum Wheel Cleaner and a green Scotchbrite pad.

Also did the same on an intake.

On my L89 heads and intake I used a Martin Senour Metal etch and a stainless steel toothbrush type brush and they turn out fantastic, I use this same product to clean alternator cases and distributors, just another way to make it happen if you don't have the tools for the other techniques listed here,

I have used Aluminum Naval Jelly made by Loctite i believe. This stuff cleans real well. If your trans case is apart, distributor, etc soak parts in very hot water first. Take a paint brush, brush jelly cleaner all around and scrub with brush, let sit on parts for 10-15 rinse off with hot water. I have cleaned factory Chevy Aluminum intakes with this stuff, comes out good.
