New Rotor Quetion, Installing Tomorrow!

I just got new rear rotors form bimmerworld, brembo blanks, big shout out to them quick shipping and awesome prices. I was reading a diy that said to clean them with brake parts cleaner to get all the dirt and oils off. Is that safe to spray the brake parts cleaner on the rotor? Also is there any "special" thing I should do to the rotor before installing to make it last longer, not rust, etc... Thanks.

Im also swapping out the pads with akebono euros.

Spray the brake cleaner directly onto the rotor face.

Also, apply a dab of anti-seize to the tip of the rotor retaining screw before installing the new rotors.

And don't forget to loosen your brake fluid resevoir cap before pushing your rear pistons back in.

The brake cleaner is fine to spray in any of the brake areas as it completely evaporates. Smells pretty awful, but it won't hurt anything. The reason to clean the new rotors is they are generally coated with a light machine oil from the factory to prevent rusting. As far as preventing rust, rotors are cast iron and will, unless painted or plated, will rust. You can paint the hats which will prevent them from rusting (use a special brake paint that'll stand up to heat). The face of the discs will rust when they get wet but the brake pads will clean these off.
