I was wondering how to clean an old saw blade, to bring out the etching that’s on it, without doing damage to the etching.
Thank you.

There is a “Gun Blue Paste” sold at sporting goods stores. Spread it on, allow to dry, use a sanding block to sand off the higher areas around the etch.

Here’s the answer your question leads me to believe you were actually looking for:

1. use a single edge razor blade, held at a relatively low angle, to “shave” rust, crud from plate.

2. use wet-or-dry paper, lubed with mineral spirits, or WD-40 (some even use Simple Green) wrapped around a block of wood to lightly sand the are you suspect holds an etch.

start with 360 or 400 grit—if necessary, go coarser, 200 or even 180. The block prevents uneven finger pressure which can obliterate the etch in no time.

don’t over do it!—etches, as opposed to stamped makers’ marks—are not deep.
