I bought some drilled and slotted rotors, it says I should clean them, but it doesn't tell me with what or how. anybody know how to go about doing this?

 

dish washer or brake cleaner.

jk just spray the rotors off with brake cleaner.

 

Brake rotors are NOT dishwasher safe. You'll get soap spots and they won't be shiny.
Soak them in soda water with a couple tabs of denture cleaner. Use Q-tips to clean out all the holes.

Or you can spray with brake cleaner and wipe with a rag, but that's not very creative.

 

haha creative. nice call.
