Cleaning a hammer Question

[MtnSpur]

The photo below was "borrowed" off GB to illustrate a hammer that has the black "pitting" or blemishes.



Is there any way to remove this kind of "hammer crud" (best description I could come up with) short of a power tool? I've always wondered why so many of the older Colts exhibit this trait. Might be a stupid question but I'll ask it anyway

Thanks fellas

I believe they corrode because they are bare steel. Here is a reference, but I have to preface with the fact that I discourage the steel wool and give this reference for the proper method to restore/retain factory like finish provided by dfariswheel.

Touching up D frame hammer?

We encountered this 'problem' many, many times in our shop.
The revolver has to be totally taken apart, and the hammer 'polished' flat on either the very smooth, fine sanding belt or if not deep on a VERY flat surface upon which a sheet of 600 grit wet or dry emery cloth, lubricated well with oil. Then cleaned and reinstalled with a light coat of oil.

Thank you A1A and RG. This forum is invaluable for information. I'm hesitant to disassemble anything other than "Leggos" even with the Kuhnhausen books due to the fact that if something bad can happen in the process I'd be the magnet that makes it a proven fact. Gunsmiths with Colt experience in this neck of the woods are rarer than hen's teeth so there isn't a safety net. Fortunately the one Colt I own that exhibits this hammer "problem" isn't near as bad as the one viewed in the attached photo. Greatly appreciate the info gentlemen
