Hello, we certainly all know,, how do I get the stupid white tracks away at the door at all places that are actually black? Normal fabric fools you can forget…at first hang around afterwards! My tip and also found and tried…Funtioniert super: von Sonax there are the damp cloths (I take the one with the yellow cover ) contains 60 pieces and with dens go these tracks great away and also everything else you want to clean in the interior so….! with 3-5 cloths you can bring the fast car clean and flashes (about 15 -20 min ) also goes great for the leather seats. Price is 6-9 euro for a can! The normal artificial parts like the area around the radio recommend to rub it easily with a dry towel!! I can only recommend this (for people who have not found anything yet)..is sure also other possibilities!! gruss Eric
