Hi all, first post here. ive a few swords from a friend that im trying to fix up, first one being a two handed sword. it has several notches, stains on the blade beyond rust, stains on the pommel, guard, etc. I've tried sever ways of cleaning but nothing seems to work. It's not a high quality sword by any means but I essentially want it back to looking good.
