A couple of months ago, after completing a sea trial on a big yacht that fairly glistened in the sun, I asked the captain, “Hey Frank, whataya use for soap? To keep your boat lookin’ like she does, I mean?”
“Orpine Wash & Wax,” he replied with a grin and more than a little pride. “Been using it for quite a long time too.”
When it comes to boat soap for the overall washdown, I’ve always sworn by OrPine Wash & Wax, a cleaner and wax mix. Buy a gallon jug and leave it in the lazarette for when you need it. I tend to mix a capful or two (depending on how dirty the boat you’re cleaning is, but no more than that is needed) with a gallon of water.
