Brake hub cleaning

What is the best way to clean surface rust from a Model A brake hub inside and outside that won't damage the hub (It is steel) ?
 
I built one of my blast cabinets from an old steel storage container. I also use a bench top type that was reasonable priced when I purchased it. Harbor Freight has one for 200 bucks. I get a pail of medium to fine grit glass beads that is about half the size of a 5-gallon pail or in a big paper bag. I've always had an air compressor so it's just one of the tools I consider a necessity. I also have a big blast rig that is used as a total loss set up but it's messy and takes protective head covering, clothing, and gloves. I've used it in a big cardboard box to save some media but you always lose some. It's an outside use set up since it just doesn't work well indoors. A person has to have breathing equipment for the big stuff. Wet media blast is kind of a new thing but it cuts the dust pretty well. It's out of my price range.

Walnut shells are good for fine work but they don't cut real hard coatings well. I don't use sand because it's too course and takes some metal with it.

The only other way is chemical strip but that is better done by professionals. I used to have a local Redi-Strip company but the EPA regs drove him out of business. You may have a local blaster that will do jobs for a price. I don't know what they would charge though. They might be reasonable on small jobs.
