if you're looking to clean the rub rail I suggest trying a magic eraser works wonders on lifelines and the rub rail on my 356, both look new.
That is the main chemical in the "roller and brush cleaner" that @Stu Jackson swears by.In case you are interested Taylor Made's recommendation on cleaning vinyl fenders: "We recommend cleaning your fenders and vinyl buoys with a mineral spirit.
I don't think that is correct. Here it is at West MarineI think MEK is no longer available in the United States.
MEKP is a peroxide. Not really the same thing as MEK. It is explosive in concentrated forms! Causes blindness etc after prolonged exposure etc! It is also one of the ingredients in the "hardener" for polyester resins.There are two different MEKs one is kinda nasty (MEK) the other is really really nasty nasty stuff (MEKP).
Fiberglass guys just call it MEK make for some confusion. I almost used MEK without the "P" to redo the gelcoat on a boat but fortunately talked to a fiberglass guy before I started and he enlightened me as to the difference. He once when he first started as an apprentice used the wrong MEK and regelcoated a boat and after a couple of hours when it did not cure his boss asked him which one he used. Apparently it is a fairly common error.MEKP is a peroxide. Not really the same thing as MEK. It is explosive in concentrated forms! Causes blindness etc after prolonged exposure etc!

This is TCE pressurized with CO2Trichloroethylene works great but I have no idea where to get it. My source went away when I retired.
And around here you get it at Dollar General for...a dollar. Pretty big bottle too. I use it on everything. Great stuff.If the rub rail is vinyl, I've had good success with LA's Totally Awesome Cleaner Degreaser. Sounds cheesy but it works.
