All About Pocket Knives

Can anyone tell me how to remove these deep dark stains from an old knife blade--it doesn't appear to be rust but maybe deep lube stains???

Kind of like cleaning carpet, isn’t it? You don’t want to do further damage and should test first in an inconspicuous area. So maybe first test on a China or low value knife. Paint thinner may work? Goof Off is a good product. 0000 steel wool only leaves very fine scratches. When you’re done wash the blade with dish soap and rinse. Use a good quality metal polish when the blade is dry.

Some photos would be handy.
