prop polishing

[PabloPicasso]

what is the best way to polish a bronze prop, in order to maximise efficiency and/or stop critters adhering to it over the season?

I always polish my folding prop each season, looks a bit tired by the end of the year but no critters or weed just a thin coat of what looks like limescale. I remove that with a scraper then clamp my electric drill in a workmate, put a buffing wheel in it and polish the prop using Faracle G3. Finish off with T Cut or Brasso on the wheel, comes up better than new. If the prop requires you can use about a 1000 grade wet and dry as a first stage. Bit of a messy job but a good result.

Any reasons why I cant use vinegar to get rid of the lime scale first?

Not sure if it's calcium based.
I find a scotch-brite pad (or wheel on a drill) works well for removing it.

Brick cleaner works much quicker

It was suggested to me over to use vinegar, chap swears by it, his prop looked pretty good.

Last year I had my new prop polished to a mirror finish, by a friend. A week after relaunching I had to have to boat lifted again because of a failed seacock, to my surprise mt lovely shiny prop had turned grey, in a week!
