So, this is where the flip up seat bottom seals with the rear cushion. Thus, it appears something is getting down in between these, drying, and leaving a stain (that is NOT being left on the seat or cushion top - only the two meet and probably trap moisture).

A fine mist hose spray does an amazing job of cleaning our Simtex.
Then, try Fantastik - is solved 90% of our other clean up needs.

Leave the seat open in the sun. I bet it disappears. Every once in a while, I get some what marks on the seats. After the sun hits it, it disappears.

Agree with RangerMTB5, I get these from time to time and will get my seats wet with clean water and let the sun hit them. As soon as it dries the marks are gone.
