Black cloth seats look slick brand new. Rideshare clients like to comment on nice new interior. When they get dirty, simple damp cloth usually removes most of the dirt in most cars. The weave in the cloth traps the dirt, and with black is really stands out.

Used warm damp cloth to wipe clean, did not work. Went with a little more detergent, used my wet vacuum attachment to get the little bit of stains out. A little more troublesome than I would have liked to regularly clean (once a week) my car for work.
