In the process of oiling the teak rails on my O'Day sailboat, I slopped a good bit of it on the beige colored rubberized nonskid. It was hosed off, but after the nonskid dried the oil left discolored "wet spots" behind. The spots are not dark colored stains like you might get from a varnish or grease, but instead are just a little darker than the surrounding nonskid and nothing (ex. nonskid cleaner, boat wash, acetone, etc.) will compeletely remove the spots. Teak oil was Boat US brand. I think it's Starbrite private labeled for them. Any suggestions?
