Lime buildup on pontoons

[TiPo]

I bought a 2005 Playbouy pontoon last year that was kept in the water for 2 years. It has alot of build up on the pontoons and I can't seem to find anything to clean them off. I have tried pink coil cleaner, CLR, and alot of other household cleaners. Does anyone have any idea what will clean them?

...sounds like it's time for a power-wash with a heavy-duty 3000psi washer.

Diluted muriatic acid, a stiff brush and elbow grease.

no, do you just brush it on and spray it off?
