can you sand blast a rotor without damaging it? let me know

 

Engine rotor? Brake rotor? Distributer rotor?

I wouldn't sand blast either one. It will damage the surface, making it hard and creating many tiny pock marks.

 

an engine rotor, and same thing with the block, and the rotor houxings and stuffor how should i clean it

 

Like Aaron said, if you sand blast it you'll destroy it essentially.

Engine rotor > use some sort of chemical. Brake cleaner, carb cleaner etc. I would say soak it in there + then use a plastic bristle brush to scrub it w. Rinse, repeat.

 

I've heard of soda blasting which is supposed to be good for thin and light metals.

 

Walnut shells would be suitable for that as well.

 

Baking soda works great, just scrub it with a brush and some degreaser first then dry it off. The soda takes the carbon off nicely and it doesn't touch any of the metal.
