Cleaning propeller

[Sailfree]

Did the last few jobs on the boat yesterday prior to launching today.

Was absolutely staggered at how hard it was to remove a deposit on the bow facing side of the phospher bronze prop. It was amost like a thin layer of concrete almost the thickness of the actual blade.

Boat is at hamble point but cannot remember ever having such a hard job cleaning prop before. Ended up rubbing it down with wet & dry 150 grade really hard work and was running out of time as it was getting dark. Probably ended up scratching/etching it nicely for this years deposit to adhere even better.

Is there an easier way to clean the prop and have others found a harder deposit than normal this year?

I use a wire brush attachment to my small angle grinder.
Takes me 5 mins and polishes up like new.

Small circular orbital sander......... almost effortless. Just keep changing to finer paper for the finish you require.

Yes me too..bit more than 5 mins but comes up nice and then 3 or 5 coats of hard a/foul.

Keeps it more or less clean for the season.
