Less than a year old (19,000 kms). Passenger seat's leather is deteriorating. Cleaning every other week with Water & non-detergent soap sprayed and Horse Hair Bristle Brush (Chemical guys brand). Driver side seems to be in perfect shape even though its used way more often. But the passenger has some darker spots while it's always being cleaned and no chemical has been used on it.
What do you guys use to clean?
