What about smudges Dick? It seems that there are quite a few "smudged" signed balls out there that this could work on. In a rare instance, a collector "might" do what you were talking about like removing a fake Maris, with a real Mantle intact. I certainly wouldn't spend countless hours of research and thousands of dollars to create a solution to remove the fake. How many would use this for good instead of Evil? We''ll, you'll have to ask Maxwell Smart about that, but it seems pretty obvious. I can't see where you would have enough customers.
Personally, if I'm such a Jack *** that I purchase a fake, I'm taking batting practice with it at the Little League field...been there, done that. I'm not chasing more bad money by trying to remove the fake. I certainly wouldn't want to buy, sell or keep one like that. Maybe if It was a Clemente, Maris, Jackie, Munson on the Sweet Spot, someone like that with full disclosure, I might take a gander.
Now if you marketed the product as an ink and smudge remover for baseballs, a guy like me would be interested and maybe save the folex for just the carpet cleanin'

What can you do for the toning Doc?
