Are you meaning the chrome tips or the box's that they fasten to?.
The tips are quite hard wearing and the most they should need is a waxing every now and then. The boxes do tend to rust a bit here and there.
This is what I do/did. Soft wire brush them all over, well at least all that you can get to, then give them a coat of heat-proof, (or caliper?), silver or aluminium paint.
Done mine about a year ago and they still look like new.
