Goof off might work...probably will. btw, "rubbing" alcohol isn't much of a solvent. It's the weaker form of isopropyl alcohol (70% or 71%) that has oils and/or fragrance added to it. The 91% alcohol is what you want. Same price usually, still really cheap, and very effective. If it's not right next to the rubbing alcohol on the shelf, it may be near the diabetic supplies.
I'm not sure if Vibram discs have added elastomers or plastics, but they're more than just rubber, for sure. Regardless, all of the likely materials are resistant enough to chemicals that brief exposure from wiping isn't going to affect them. Soaking or long term exposure to fumes might be a different story.
