Great scores!
If the meat grinders are the old school kind, after you've thoroughly washed them, you can boil them in a pot--you'll be amazed at the crud that will rise to the top (says she who knows from experience when she bought a second-hand grinder last year). Mine is great now, but there were little bits that I just couldn't wash off when we first got it so hubs decided to boil it to make sure it was sanitary.
