I have a brown backed on dirt on my life lines and rubber rub rail. I have
always hosed off the boat after every sail and this stuff just won't come
off. Whets the best cleaner to remove this stubborn crap from my vinyl and
rubber parts of the boat.

Thanks in advance

I honestly don't understand the first sentence in your question. I know
Laquer thinner will take no prisoners when it comes to cleaning rubber and
vinyl.
