Thanks! I wiped the metal down with rubbing alcohol and all the filings cleaned right off with no ill effect! Used some veg oil to lube and everything worked out great!My shredder was shipped with food grade Glycerin as lube. I’ve never used soap and water so I can’t say about that. I ran it backwards and forwards and blew it out with air. If you don’t have a compressor you could use the bottled compressed air in a can like used for cleaning debris from computer keyboards. Lube it and go. You’ll feel it when the burrs are gone and it smooths up. The case of the tobacco is the big deal, I run mine just dry enough to not crumble and turn to dust. Just avoid enough moisture to start gumming up. You’ll develop a feel for that, too. Enjoy your shredder.
