If you are looking strictly for rust prevention on safe queens, then your needs may differ from wanting a good lube that is also good at rust prevention. I have never used Renaissance Wax, but it's recommended for carbon spring steel replica swords, and many museums use it on real swords. For a straight lube, it is hard to beat Militec-1. The problem with Militec is that it is
horrid for rust prevention. If the pivot area is uncoated, then the Militec is a bad idea:
CPM-M4 Presidio blade. Yes, that is surface rust on the pivot from the factory-applied Militec-1. I no longer use Militec on anything I want to keep rust-free. Fortunately, Weaponshield and Tuff-Glide/Cloth keep things just as slick as Militec, but their rust prevention is light years beyond it.

I've been using 3-in-one oil for as long as I can remember, the stuff from the little metal tin. Has anyone else had experience with it? Always worked fine for me!
I use drug-store mineral oil. It's food safe, odorless and best of all it ensures that my folding knives are smooth and easily flickable.
Y'all have given me an idea for my next rust-prevention test that will be bigger. I forgot that I have some of each. I should have included them in my first test.
mineral oil
Mobil 1
3-in-1
Weaponshield
CLP
Tuff-Glide/Cloth
WD-40
Militec-1
Froglube (someone is sending me some to test)
Disotec XFR
Armadillo (supposed to do what Renaissance Wax does)
anyone else want to send me a sample of something I haven't listed? It would need to be enough to cover a 3" x 6" steel plate on both sides. The test will be conducted in late February.
