Ah, the pink stain issue...

I had this on one cushion of my '15 G23. They replaced the vinyl under warranty.

A common myth is that pink stain is mildew or mold. It is really a by-product of a bacterial microorganism. This organism’s by-product, a pink/red dye, is soluble in plasticizer, which is the main ingredient in upholstery vinyl. When this by-product comes in contact with vinyl it causes the pink stain. Wind or rain can carry these microorganisms onto your marine upholstery. These organisms can live and grow in the foam cushion. This too will cause the pink stain on the vinyl.

Try Barkeepers Friend cleanser, it has a light acid and works well on removing stains. You can purchase it at your local grocery store...
