Hello, since my best wife of all yesterday fell unnoticed a chocolate egg on the passenger seat, which she then ‘seat’ in the seat cover for about 200 km. (V70 MY 2002, partial leather anthracite, seat heating). The cleaning action with normal fat solvers brought so far no real success. 1. Who knows good cleaning tips? (If it matters, it was an after-eight egg, and only borderline tasty.) 2. Is there in case of emergency besides the friendly another source for a replacement cover (possibly needed)? Exchange should not be a big problem, or does the seat heating cause problems? Thanks. -harka
