Does anyone know the best and easiest way to clean algae off of pontoons?

Dried or still wet? Probably the best thing for either condition is the pink coil cleaner you can get in gallon jugs at air conditioning supply houses. Just slop it on with a paint brush and rinse with a hose after about 4-5 minutes. Leaves a clean but chalky surface. Next step is polishing (a real chore) if you want a shine.

Here's some info.

for algae go to the car wash and use the engine cleaner then blast it good
