Refinishing Cast Iron Wheels

First of two simultaneous responses --

A. Wire brush them clean of dirt and rust, and then spray two or three coats of low gloss clear lacquer. The more elbow grease you invest, the better they will look.

Second of two simultaneous responses --

A. 5% citric acid ⇦this on eBay or Amazon [affil links] solution, soak them. That will get most of the corrosion off, then I suggest going over them with 000 steel wool ⇦this on eBay or Amazon [affil links] to get and residue off then rinse with water to make sure there is nothing left. Afterwards I suggest painting with Rustoleum black high gloss. If you have any other rust on the cart I would say take a wire brush to it, or #01 steel wool [affil link on Amazon] depending on the severity of the rust.

Additionally the wheel lugs may be a bit rusty, take a torch to the nuts and try to torque them off while they are hot, if that doesn't work take them to an auto mechanic and see if they will pop them off with a impact wrench.

A. Hi D. I'd take a ? and then I'd go and ? the wheels with it :-)

Seriously it's hard to offer an answer to a vague proposition ... but if there is nothing left holding the wheels on except friction, then spray on WD-40 ⇦this on eBay or Amazon [affil links] or Liquid Wrench, whack something with a mallet to try to set up some vibration or movement so you get a little penetration of the solvent, then attach the biggest "wheel puller" that fits, and hope for the best.

Sometimes nothing will work. I had an old MG-B with wire wheels and had to pay the mechanic to take a torch to one when I got a flat tire :-(
