I put PRP covers on the bucket seats I installed. They're vinyl so you'd think they'd be easy to clean. Surface stuff comes off easy but there are some mud splatter stains that you can scrub forever that just don't come out. I haven't used any harsh cleaners, just soap and water. When they're wet right after scrubbing it appears that they're gone but once dry they rear their ugly head again. It's an off road machine so no big deal but anything you put on or in these machines is never the same again.
