Recently cleaned up a couple of Stanley block planes. I used citric acid and scrubbed the parts with a scrubbing pad and a brass brush. Looking at the cast iron body I noticed that it has turned yellow from the brass brush. Anyway to remove the yellowing short of sanding it?

Use metal polishing compound.

I use a brass wheel all the time. I’ve never heard of the issue you described. i’m not sure what it would be, but brass shouldn’t leave anything.

I suspect that is a non-brass brush masquerading as a brass bristle brush.

I’ve used brass brushes and wheels for decades with no problem.

Tried to get the color to show in the pictures. I still need to sand the soles smooth since the clean up but was concerned in ruining the nice full metal color on the sides by polishing it.

That’s what I kept thinking, scrubbed harder and made it worse. But it’s shiny yellow color so it had to be the cheap brass brushes I got at Wal-Mart. Since these I only used a Scot brite pad and hadn’t had a similar case.

Now I only need to remove it without destroying the dull metal patina. Not too concerned with the bottom but the sides have similar spots.

Have your say...
