Hi all. Just got my Q5 back from the body shop and the interior is a bit dirty (in particular the dash, arm rest and a couple spots on the leather seats). I'm going to use 1z Cockpit on the dash area, but can I use it on the armrest/leather seats as well (I don't think I can but not sure)? Should I use opticlean on the armrest/leather seats? I don't have too much else at my disposal right now. Worse case I'll just try a little water. Thanks for your help.
