Hey guys, the reason that pontoons are made of aluminum and not steel are weight and rust. Aluminum does not rust, but it does corrode.
The corrosion by-product is actually a protective layer to the metal. Steel in order to form a layer (called magnetite), it must go through a passivation process and then stay in that environment, Aluminum is different.
Any time you acid clean a toon, you are accelerating the corrosion as the next season, it will again corrode once in the water.
If your toons darken that's a good thing. Leave them that way.
If the toons have organic material on them, that's different. But don't use acid to remove it.
