Well there might still be a little left in it, Russell, but not very much. I would liken it to a new piece of sandpaper vs a very well used piece. And the more I use it, the softer it gets. I just think it can get into the tiny nooks and crannies of the surface better. I think the ss scrubbie just floats over a lot of the tiny pits and pores. There are other things I use, like a toothbrush for tight places, but for wide open spaces that worn scotchbrite pad does a great job. If I saw any damage, I'd stop using it..there just isn't any.
