Half Shafts Rusty - What can be used to remove rust?

[1badzr1]

Hello,

I received the CR1 on Tuesday night. To say that I am happy is an understatement. I spent the better part of the evening detailing every part of the car. Didn't go to bed until 1AM.

Now I need some advice and recommendations. When I had the CR1 on the lift I noticed that the half shafts are rusty. When I pass my hand or rag over them the rust is powdery. Wha t can I use to remove the rust to get them back to silver? Also, what are they made of steel or aluminum. The rest of the car shows no rust. On my 95 they always remained rustfree. I'm just surprised that the Half shafts are in this condition.

Your help is appreciated.
Regards,
Ben
