OK here is my 2 cents...Never use steel wood...what will happen is that pieces of the steel wool get in bedded into the metal and the the steel wool will rust it self. Scotchbrite pads will work or go to your nearest Harley Davidson dealer and ask for a product call Never Dull. Now I know this is going to sound dumb but if you leave the blade out in the sun to warm it then use Easy Off Oven Cleaner it should come off. That is a old trick us motorcycle builders use when our customer get their booths melted onto their pipes. Good Luck.
