Reading several older threads it appears that several of you use brake cleaner to remove oil and grease from the bolt/action.

Is there a specific type of brake cleaner that you should use? Was planning to use the red CRC.

Any chance of removing nitride coating on bolt/action?

Brake cleaner is a great degreaser. Being that nitride treated actions aren't just a coating but penetrate into the steel you won't remove it. But I would test on an inconspicuous spot first to make sure it doesn't discoler it.

I’m not sure what the CRC is made from, but the cheap stuff is acetone in a spray can. Plenty strong enough for degreasing.
 
On oils, greases, and wet-fouling you find inside fired guns, it's better to use 90% or 99% rubbing alcohol - put it in a spray bottle from Home Depot or Lowes if you want to be able to spray deeper into an action. It's non-toxic, and works as well or better than brake cleaner, and is generally a lot cheaper. Only use solvents like brake cleaner or acetone on hard deposits, polymerized/baked fouling, or getting into adhesives such as thread locker, which is where they excel beyond what rubbing alcohol can do.
 
Like RockandSage said, be very careful around anything you don’t want to strip the color off of or make poka dotted when spraying acetone. I take just the bolt and go completely away from the gun.
