Remove stains on tower

[MNStCroix]

When I got my boat back from offseason storage and maintenance it had what looked like grease stains on the base of the tower. Not significant but annoying none the less. Here are the pics. My normal Boat Sauce exterior cleaner has no effect on them.
Does anyone have any suggestions of what has worked or what I should try?

Thank you

Without knowing what it is, it's hard to know how to clean. I've had good luck with Comet cleanser (a little abrasive, a little bleach) for stuff like that, but Barkeeper's Friend (oxalic acid) also gets out some stains that seem otherwise impossible to get out. Best of luck and please let us know what works!

Can’t say what to use for cleaning, but realize I am pretty sure the tower is painted and not gelcoat.

Try magic eraser.

Try crazy clean but be cautious on getting it on your seats or cushions.

Thanks for all your input! I found this product at Fleet Farm and it worked like a charm. Sprayed it on, let it rest for a minute, wiped off.
