Did I get your attention? But seriously, folks, my formerly nice white juggling balls have red smudges all over them. I had them stored in a drawstring bag provided by the juggling store, which I think were made for clubs. Now, it seems like I made the unfortunate mistake of storing four white juggling balls in there, too. Some sort of chemical reaction must've occurred --- I don't know if it was the unusually warm weather or the wipes I was using to clean the clubs. All I know is that some of the dye must've rubbed on the juggling balls at some point. Any tips on how to clean dye off a ball that are PVC and/or silicone?
