Rust Removal, In those sensitive areas Options

[Loser_Cruiser]

What is the best method for rust removal on parts that have machined or bearing surfaces?

I have some spindles that have surface rust that I would like to remove but the machined and bearing surfaces are still nice and clean and would like to keep them that way.

Thanks!

For everyone...
Take a standard 55 gallon drum.
Cut retangular port, install piano hinge and latch on side.
Install 2 inch pipe through lid and bottom, centered.
Install standard shaft carrier with sleeve bearings, one on bottom and one on lid.
Terminate shaft-end by welding solid shaft with key.
Install 10" pulley on keyed shaft, using grub-screw locking ring.
Weld or bolt together base frame from two by two steel angle. Base footprint
design needs to be sturdy enough to support assembly and parts...(250lbs dynamic).
Locking sissor frame okay, if sufficient in design.
Install retangular motor mount on frame.
Install two stiff deflector rubber blades 180 degrees apart on the inside outer wall.
Install 120VAC Swamp Cooler electric motor onto mount with 1/4 solid rubber pad.
Install standard outdoor light switch housing to frame and wire motor and install
switch. I used a dimmer switch.
Insert abrasive media, about two to two and a half bags.

Now you can tumble suspension parts or anything that fits in the 55 gallon drum.
I made a smaller coffee can size container inside to tumble smaller parts at the same
time without have to look for them for an hour....
