Dirt and Grime
Steering wheels see a lot of use on a day-to-day basis, and all of that dirt, grime, grit, oil, etc. builds up over time. That’s why it’s important to make sure you clean your steering wheel on a fairly regular basis. Especially if you don’t have a cover on it to keep the worst of the problem from sinking in. Cloth-covered steering wheels are fairly easy to clean, as it’s usually just a matter of spraying them down and soaking out any stains. Leather ones can be more difficult.
