Easy Off oven cleaner works good but, I would go for the cheap stuff at the Dollar Store if possible, better yet, what ever the Wife has on hand. lol. Right now I am useing bleech and I agree it works fast in most cases but, right now I have a bumper from a '50 Chevy pickup thats been soaking for two days and still has a little chrome. Just a fun test, I can probably brush the rest off right now.
