What sm1ke said about using water. At least once every week/2weeks, I take a clean cloth with water, ring thoroughly, and wipe down the steering wheel, seating services, armrests, dash, and even hit the turn signal & wiper stalks, door handles & pulls, and shifter. The last thing I do is wipe the floor mats (WeatherTechs) and door sills... I’ll vacuum the floor before wiping down if there’s a lot of dirt.
You’ll be amazed at how nice the surfaces, especially the steering wheel, feels with just a wipe down. This will prevent dirt and grime build up on surfaces which can slowly degrade the various surface finishes.
Every so often (couple times a year) I’ll follow up with Lexol Conditioner on the leather surfaces. I typically use Mequiars Interior Detailer on the dash and door panels.
