I pulled of the vinyl wrap. It's badly stained. The cover must have been put on a long time ago when this was a new car. The wheel is in spectacular condition. No splitting or cracking at all.
I used a scrub brush to scrub the cloth section to soften it up, then vacuumed the dust off and wiped with a cloth with warm water. They're very nice now
I had to resew some of the seams, then i sanded the vinyl and sprayed adhesion promoter and my interior black on them. I tested this method for durability btw. PM me if you want more information.
