Hello, a tip for people with Orion grey leather seats (others as well). Since I travel a lot in dark coloured jeans, the light leather seats have over time got a dark veil. I tried everything possible and above all expensive but without any real success. The greasy “leather care products” that can be bought like this are actually only expensive. I found the ulitmative solution today. I am from the best wooden floor soap (Fa. TripTrap from Denmark from Palm- and Linseed oil) prepares a solid foam and cleans the seats with a microfibre window cleaning cloth (the one with Flor). First rub well with the foam, then dry with a terry cloth and then the same. The effect was brilliant. The seats are as new. No greasy shine as from the expensive means, fresh color, matte look and silky soft through the re-greasy soap.
