Gripper seat cleaning tips?

Does anyone have any tips on getting black marks off them rough gripper seats?

Anyone have a 2021 CRF450 and have trouble getting stains off their seat? I’d imagine these type of seats are on the 250s as well?

If you look at Ryan Hughes videos with riding tips in this bike, his seat has stains as well.

I’ve tried Muc-off and some generic cleaner like muc-off which usually cleans up the seats I’ve had in the past quite nice but it won’t touch these stains/marks. Would petrol/gas damage the seat cover?



This is the best picture I could get as it doesn’t show up very clear on the pictures. It looks worse in natural lighting outside and there’s a few of these all over the seat.


Thanks.
