But voila! As we were cleaning the lazarette, I came across some Soft Scrub. I had heard something good about it years ago, so I bought some for the boat, but hadn’t thought twice about it in a long time. It’s definitely not good on fiberglass and probably wouldn’t make a suitable day-to-day cleaner even on paint.
If you own a boat, I’m sure you know what I’m talking about. Those grimy black streaks – I don’t even know what they are. But they are both common and annoying. Regular soap doesn’t get them off, the “black streak remover” they sell is expensive and not particularly effective, and plain elbow grease is not even all that great.
