I asked several times about Tuf-Glide/Tuf-Cloth about a week ago. Received no feedback specifically on those products, but there were several recommendations in the way of Renaissance Wax; a "micro-crystalline wax polish" used by museums the world over for protecting priceless artifacts. I snatched a 200mL (probably a lifetime supply) of the stuff for about $20USD off of Amazon; have not used yet. By all recommendations and indications it's inert enough to use on just about anything (wood, metal, bone, ceramic, eh...even photographs). Jaxx said that a knifemaker put several protectants to the test on uncoated blades and Renaissance Wax was the clear winner ("by a visible margin," if I recall correctly). No definitive information on its safety regarding food-grade cutlery, but it seems unless you're eating the stuff directly by the tablespoon, it shouldn't affect bodily functions.
That being said, I have found that Tuf-Glide, while it works really well in lubricating parts and providing a dry layer of protectant, needs to be reapplied every few months. I live in a high-humidity area now, and a higher-humidity area (a got-damn rainforest) before that, and Tuf-Glide worked beautifully but would expire (?) and would require additional application within 2-3 months. YMMV, as they say, but it's good stuff if you don't plan on food applications. I mean everything is bound you give you turbo-cancer in adequate amounts, but as I understand it Tuf-Glide/Tuf-Cloth is fairly toxic and not recommended for cutlery intended for food use.
As a dry lube for moving parts it's pretty great though. I used it to lube the bearings on a ZT-0561 in said rainforest (northern coastal South America--it rained every day, constant 95% humidity) and was enough to prevent rusting/seizing of the IKBS ball bearings. I had a BK-2 (1095 steel) and a CRKT Chogan Woods Hawk (1055) there as well (by the way, tomahawk in a rainforest is useless unless you're using on jaguars or caiman--a Cold Steel Smatchet [I know, blasphemy, but it was the third world and there were customs/shipping/transportation issues] was the winner in the jungle) that I used it on and neither rusted; I was there 14 months and the BK-2 looked brand new at the end. The takeaway is that through consistent (read: every couple months) use it prevented rust on high-carbon blades, presumably at a lower grit and higher carbon content than satin Busses.
For INFI I've found it doesn't affect the finish; I seem to recall another BF member mentioning that he wiped down each of his nicer blades with a Tuf-Cloth before storing back in his safe. I assume it presented no issues to him.
But as far as top-notch rust-/oxidation-prevention, it seemed Renaissance Wax was voted the winner with some firearm lubes/protectants as a close second (Froglube, Slip 2000 EWL). Duramax has some rust-/oxidation-prevention recommendations as well, but he's reluctant to share those so you'd have to hit him up in a private fashion. **(I'm not calling Duramax out, he has good advice, but he's trying not to conflict with BladeForums sponsors and whatnot.)
