Neutrogena® Make-Up Remover Cleansing Towelettes did a great job on many of my sticky surface, with a lot of gentle hand rubbing. Some surfaces are black plastic and some are optioned as “graphite”, which is basically black with a gray color on top, and then all had a uniform finish to give them a tactile feel. It’s this finish that breaks down, and not just on Jag but other high end manufacturers, Canon binoculars etc. The wipes are best on black surface, but too much rubbing on the graphite ( if you have that option) will reveal the black underneath. I’ve also used baking soda with some success but it’s messy. In some models (XE?) jag did a factory recall and replacement. My dealer screwed me over, only replacing the bare minimum under warranty. Which is why I’ve since bought two Audis and zero Jags… in fact I don’t know any jag owner who’s bought a second one…the Australian operation is such an underperforming busines…
