Don't worry Ridolpho I was pretty skeptical about it until the old chap showed me removing surface rust, the finished product looked just like it has left the factory, I buy the stainless scourer pads (Non-soaped) sometimes the threads get caught and they unravel a bit but thats no big deal you get a fair bit of wear out of them however I am not brave enough to try the ordinary stuff.
Ringo = You may have to go to the local supermarket, go to the kitchen section and look for them there they should be there somewhere but don't get the soaped ones.
