After last fall my Lund had a lot of “old man river” stuck on the hull and it was starting to look pretty rough. I started looking around on line and saw that there were a lot of products specifically marketed for cleaning boat hulls. I also noticed that they were about as expensive as a good 5th of Whisky. Last weekend was wandering around the automotive section of a department store and came across this stuff called Simple Green. The claims on the label sounded a lot like the boat hull cleaner stuff….biodegradable, non-alkaline, etc. They wanted $4.00 for a big spray bottle so what the heck.
I sprayed it on and let it soak for a few minutes, and I’m happy to report that the scum wiped off with a paper towel! Now I’m sure there’s more expensive stuff that would work better, shine up the aluminum, etc. but for the price this worked pretty darned good.
