Clean new brake rotor with brake cleaner before install?

okay, so if you don't use brake cleaner to clean brakes, what do you use it for?

Maybe he uses it as a substitute for Dawn and washes his dishes with it.

Just did rotors on my Atlas. Out of box onto vehicle. Never washed rotors prior to install.

That's what I have always done. I didn't see any warning about pad contamination on either the box of the pads or the rotors. I also am not sure if the factory would spray them like that when they build a new car, it would cost too much.

I always do.

Here I am just doing a pad slap on the truck, OEM rotors with no rust or warping. First time I will be doing it but they are in such good condition I can't bring myself to throw them away, barely a wear ridge. I guess being in the flat south most of it's life was a real advantage.

People say, "warsh" for wash and, "pawrs" for paws (dog's feet) frequently.
Typing it and ignoring the red underline is something else.

I've heard of Wappers for Wipers, but only in Kentucky.

Have always installed new brake rotors on my cars as is right out of the boxes, until today I saw a few videos on YouTube that people spray them down with brake cleaner then wipe down. Is that a common practice? or something not that common?

YES

Never installed Geomet rotors but my SOP with new/machined rotors is a bath in hot water and Dawn/Dr. Bronzer’s soap with a Scotch-Brite to knock down the metal filings and then chase them with brake clean after towel dry.

If the surfaces are not coated, then Super Clean full strength plus a stiff brush to remove the oils. Follow up with brake clean.

If the surfaces are coated and the pads are aggressive enough, then install as-is. Sometimes I'll use a roloc disc and buff off the coating.
