So i finally got up off my *** and took apart my motor. i did some searching and decided to soak the rotors in simple green. i read in another thread that after you soak the rotors in simple green that you should rinse them off. So i did that, dried them off, well actually i only rinsed one off cuz it was finished faster, and i put it on a shelf. a couple days later it had a bunch of rust on it. i guess my question is, are they still useable? and what did i do wrong? how can i prevent this from happening in the future? i wasnt planning on using these rotors anyway, i was gonna use some s5 rotors, these were basically just practice.
thanks

 

Isn't Simple Green pretty much water-based? or you use water to dilute it sometimes... anyway, that's probably why they're rusted.

 

rotors are metal, metal rusts unless you put a protectant on it after rinsing it with water and handling it. rotors originally were zinc plated but most of the time more than 50% of the zinc plating is gone from age and wear.

 

I don't think they would be damaged from a little surface rust... Maybe soak them again in that simple green, or use steel-wool to clean off them rust, rinse them, use compressed air to dry them (cavities especially) and then spray them with a nice coat of WD-40. Probably not a big deal.

 

god damit, every time i see ur car..............stop posting erick it makes me want ur car..............I"M NOT CHEATING ON MY CAR...

as for the rust on ur rotors, you are going to have to clean them off with something, steel wool i dont know about but that might work and a coat of wd would work very well.........but anyway get them thangs clean so i know that's the way to go
