My steering wheel has gotten pretty ugly. It's like whatever was on there has started to degrade. Living in an ocean climate, it's thicker air, and I can tell this espeically in the mornings and after rain. When I hold the steering wheel a while, it almost feels sticky, and leaves a residue on my hands. Is there any way to clean this a bit? It almost feels like there's something caked on. Hot water work? Or is there something better out there to use?
