Hi, I have a few parts that have that oxidised white powdery layer like in this picture - http://farm4.static.flickr.com/3230/300 ... f4.jpg?v=0

What the best way to get rid of these unsightly patches, I've read nail varnishes, sandpaper, and vinegar work.

Can anyone let me know if any success or just leave it and don't mess with it?

Many thanks

unfortunately, that 'worming' is aluminium corrosion under either a lacquer or powder coat. the only way is to remove the whole coating and then sand & polish.

I'm afraid he's 100% spot on, the only way your going to get to that corrosion is to remove the lacquer, the problem then is where you can stop without the resulting join being highly noticeable when new clear coat is applied.
