Cleaning aluminum Budd extrusions

Talcum Powder will should remove the polish. We would use it to clean polished propellers, spinners and other other polished surfaces on Light aircraft.

I'll try it.  I seem to have lots, for tire changes.

Great solutions on removing the compound.

Are these the Lionel Post War bare aluminum type cars? Or the modern bright finish ones?

2- rail forum - sorry.  But bare aluminum.  I believe Lionel extrusions were anodized, which makes onset of corrosion slower, and when it occurs, more difficult to remove.

As far as I can tell, it is difficult to Alclad extrusions, so corrosion is almost automatic, and pitting can become a serious problem.  Using steel wool acerbates the problem, since tiny fragments of steel act as the cathode.  Steel wool is forbidden around aircraft, and ought to be forbidden around model trains.  Working more on the problem today, after a short maintenance flight.

Tried the talcum.  Works well - maybe better than flour.  Same principle, I guess.  Everybody knows that talc can be purchased as Johnson's baby powder for cheaper?  Or at least that was true before the lawsuits?

I brought them home.  The one on the left is about halfway done; the one on the right is about to be started.  Ninety-seven degrees at the airport, and here I can watch the Senate hearings while I attempt to polish.
