I'm doing some work on my mother in law's 2002 E320 4Matic. The car has only 80,000 miles on it and is in good shape, but the interior has seen better days: It's dirty and has makeup in many places.
As a test I applied Leatherique to the rear left side seat. I let the conditioner soak in for about 20 hours, then used the cleaner and followed up with a damp towel. Im very pleased

The leather is now nice and clean, and much softer to the touch.
I'm going to do the rest of the interior this week
