Hello all,
did a search and couldn't find anything that adressed this:

so I just bought my hunter 212, and I'm pretty happy for someone who is so far mainly spending his sea time scrubing and cleaning. which is ok, when the cleaning works....here's my gripe:

The boat came w/ a set of very dirty cushions (cabin and cockpit), the cabin cushions are made out of plastic/leatherette material, cockpit cushions are plastic mesh. Now I've cleaned and scrubed them to death, and most of the stuff has come out (used Oxy Clean), but some of the more stubborn black dried oil/grease type of stains on the cabin cushions are refusing to go no matter how much I soak/scrub. Any idea on a cleaner that would take care of that?
thanks !
