My experience is that your butt will wear it off over time. To speed up the removal, try a gentle grease cutter, like diluted Simple Green. Or even Dawn or Ivory dish soap. I'm pretty sure diluted methylated spirits (denatured alcohol) will remove a lot of it. Methylated spirits is just ethanol (ethyl alcohol) the type we drink, only mixed so we can't drink it. I use a mix of 50% distilled water and 50% of an off-the-shelf 70% ethyl alcohol. Dilute it even more, if necessary. I use it to clean all sorts of things at work. A good grease and dirt cutter, it removes fingerprints and age from computers and LCD screens. I buy it at Walgreens. Please don't get the wintergreen mint smelly stuff. From what I see on line, Armor All is believed cause the vinyl to crack way too soon. Get some Corbin Saddle Cream. http://www.corbin.com/care2.shtml http://www.corbin.com/accessories/conditioner.shtml Note: a 50%-50% mix of isopropyl alcohol and distilled water is preferred for cleaning LCD screens. Note #2: Most windshield and faceshield manufacturers don't like alcohols used on the plastic. There is a chance of the coatings being removed. (But camera lenses that have coatings, are cleaned with... alcohol...) edit: oh yeah, and use those micro fiber rags, they rock. Cheap at Dollar Stores.
