I have recently just finished a knife 1084 steel, polished and buffed, put a coat of renaissance wax on it, wrapped it up in a crown royal bag over night. Went out next night to sharpen took out of bag and its cloudy on 1 side and just a little bit starting on the other side. My shop is hot and humid as it has been 100 in Iowa for the past week. Anyone have any ideas as to what is going on?

1084 polished blade / rust problem

Well I kind of thought that also but was not sure. The only good thing was it wasn't sharp. So I guess back to the buffer and then re-wax and hopefully it does not happen again.

Trying to stop that steel from rusting is work. It wants to patina just existing there. Maybe coat the hell out of it and put it in a safe that has a dehumidifier.

I rely on BreakFree CLP, but ordinary Vaseline will protect against rust.
what is the correct type of oil?
I wouldn't worry about it, carbon and tool steels are meant to be used, if storing them put some 3 in 1 on the blade, if unsavory aesthetics start to appear, apply some flitz.
I cut some bloody beef with a k390 knife of mine and the darn thing started developing rust spots 5 minutes later, I was blown away, so I put flitz on it and came right off, the steel is beginning to become more "tame"
ultimately knives just want to be used --- and will develop a "wear and tear" coating that helps battle rust and stains and stuff. My opinion

Not sure of there is a 'correct' oil for steel if you're just needing something on the fly... Are there incorrect common oils that dont protect against rust/oxidation/patina, for that matter?
On my carbon blades I've used everything from mineral oil, Ballistol (mineral oil based), lip balm (in the woods use what you have), various cooking oils, chicken fat, etc to protect them between use.
For long term storage, oils that don't go rancid tend to be a better choice (Ballistol, mineral oil, gun oil, 3-1, etc), choose which one suits the intended use... mineral oil for knives that will cut food, and for general utility knives the type of oil has been less important to me.
I'm with the others who mentioned letting a patina form though. In my experience, it's effective passive mitigation against rust. My daily pocket carry is in 26c3, which is just as bad of a rust magnet as 1084 can be when it's straight off the grinder. After forcing a light vinegar patina on it I never have rust issues with it. I wipe a thin coat of Ballistol across it occasionally, otherwise I just keep it wiped clean and dry it off when necessary.
If you're trying to keep it shiny, and dont want patina, then youll need to keep it oiled. Just be aware that you're going to have to be very dilligent about what you choose to cut with it, and to reoil after use.
