My question is what should I use to clear the prop of the remnants of
the barnicles (sand paper? if so what grit) and should I treat the
prop with some kind of anti fouling paint?

I have a prop that sounds like yours (3 blade max prop).
Out of the water I used a wire brush on a right-angle grinder to
get the critters off and polish it up (they make these for drill
motors, too).

I was told by our boat shop that most anti-fouling paints will
attack the metal in the prop and you shouldn't paint it.

On their web page, PYI (makers of MaxProp) sell a paint just for
props. My father-in-law used this and said it didn't do any good.
