I have become the new owner of a KT-34XA which has never been deployed.

Original owner bought it 3 years ago, and it has lay on the floor of his car
port ever since. So it has been subjected to rain, bird poo and mice. The
main elements (mainly the boom) show the signs weathering. Very dull gray and
an almost dusty texture.

What would be the best thing to use to clean the elements, before grease and
assembly?
