I use the Mcguires cleaner wax from the local O'reily's. It waxes and it clean some stuff off of the hull. I also use that on my spin pole.

I have used the Holmekol and it's very nice, just a little expensive.

What I generally do is at the beginning of the year, I use the Holmekol for the "base" if you want to call it that, and the rest of the year use the McGuires.
