How do clean up your props, shafts and rudders?

[MikeJ42]

I see a lot of people using sanding disks on drills etc, but surely that would just score the surface making future growth more prolific?

Is there a better way?

You can use brick acid to melt off the lime deposits etc, but be careful what you put it on. Last year, I used a nylon wheel to scuff off the dirt and small barni's then did a quick clean with some brick acid, then final clean up. WIth regard my bronze props, they get a polish then a coating of prop-shield. The PS stays on for about 2-3months then its all worn off (and yes I did heat the props up and follow the app instructions to the letter) and you're open to the usual elements. A mate of mine used MC chain lube and it stayed on nearly as long and its much easier to apply, so might try that this time around.
