@2007LucerneCXL has already mentioned using LEXOL to clean and condition your steering wheel leather. I will just add to what he's suggested. Just about any cleaning product designed specifically for leather will do the job. I'd avoid using a generic cleaner.I'm curious bout interior cleaning products. My hands sent always clean as I'd like em when I get back in the car, as I'm working mobile right now. What's something good to clean the steering wheel without ruining it or the controls. I can be careful bout not getting anything on the controls of course. But the wheel itself, it doesn't feel as clean as it was new, I wanna get that back
Applying the cleaner to a brush or directly on the leather, and then lightly working at it with the brush, will remove most of the nasty stuff that sticks to the wheel over time. Finish up by wiping it down with a microfiber towel to achieve the original matte finish.
This is the most concise video I've found explaining the process. I have never used Chemical Guys products, so I can't vouch for them, just using their video.
