Hello! I'm brand new here and have joined mostly for the purpose of asking for help in regard to bayonet preservation, as I have a handful of bayonets in my collection in various states of decay. I'll preface this by saying that I am aware that the goal is to preserve the bayonets in their current condition, not to make them look brand new.
Long message, I'll try to condense it as best I can:
I've been trying to research what I can about what to use and how to do it, and while it can be overwhelming, it seems it's best to pose a question like this to the community since there are a lot of folks who have experience and success in this type of preservation, despite the many differing opinions and suggestions. I've heard folks using WD-40, paste wax, Renaissance Wax (kinda interested in this one), vinegar, 50/50 mixtures of transmission fluid and kerosene, kerosene at full strength with a bronze bore brush, and so many more (and then folks going against the above suggestions, which adds to the fun and confusion).
Heck, my little brother (who has a 1912-dated pump-action shotgun and has done a bit of preservation work on that) suggested that I use bore cleaner, a soft brush (likely something like nylon or bronze bore brushes), and a thin layer of synthetic oil.
The use of steel wool, "Kroil" (a penetrating oil only sold in the US), and bronze-bristle brushes have been suggested to me for one bayonet already. I have picked up #0000-grade steel wool from work, all I'm missing are bronze-bristle bore or detailing brushes, and some sort of liquid or wax. A few of the bayonets (the M1892 Krag, Pattern 1888 Lee-Metford, and M1866 Chassepot) shown in this post look to have some spots of red active rust, which I'd like to remove as safely and best as possible without damaging the finish. The others (the Pattern 1853 and 1936-dated M1884/98), look to be in a condition where they might not need anything since the rust is a darker brown, but I'm both tempted to try and clean them up, and scared to do anything to them for fear of damaging them much further. As for the wood, the grips on the majority of my bayonets look fine, but perhaps it wouldn't hurt to put something on them to keep them looking as they are and prevent further damage from the oils of my skin when I'm foolish enough not to handle them with gloves.
What are the best things that I should be using to preserve (the metal more than anything, but also the wood) my bayonets, and how should I be doing this?
