    You can blast it, but no matter how good the masking is it still gets in.

    I used soda for the blast media and then You can wash it and it dissolves.

    I still stripped the diff and cleaned it out after cleaning though.

                    AndyP,
                    Their service was not cheap, but final effect is nice. I don’t know what exactly they use, some sort of chemical plus small plastic balls.
