approach for cleaning prop

[rperret]

Now that the boat is hauled, and engine winterized (most satisfying when you do it yourself and save $$$..), time to clean my martec prop.

Of course there is still residual barnacle crud on the prop after the power wash, and was wanting to get the board's input on best cleaning approach?

1) 400 grit wet sand?
2) noxon?
3) some mild acid (that won't harm the bronze)

My goal is to completely clean and polish it - then try some of the anti-fouling methods that have been mentioned on the board next spring.

Thx

I simply use a brass wire brush attachment on my angle grinder - after knocking off all the barnacles with scraper. The 400 grit wetsanding could be used as a final finishing treatment - but I've never bothered.

Personally, if you're planning on coating with anti-fouling paint next season, I would hold off on the acid wash until then. The bronze will oxidize over the winter.
