Hello all, I have a E270 CDI Wagon -05 and also with pebble beige interior. No matter what clothes you have, they discolour the seats and the fabric.
I use Driwash'n Guard Leather and Vinyl treatment and Upholstery, Fabric and Carpet treatment.
It's very efficient and gives a fresh scent in the car! The leather and upholstery looks like new.
I live in Finland and they import it from the U.S
