Duct tape, it fixes everything.
Trumpet valve lube, WD-40 (VERY little), 3-in-1 Oil, will all work.
Would baby oil work? Silicone?
No, that would ruin your bearing. Stick to what I suggested.
I find it to be too thin. My bearing doesn’t quiet down even after drowning in it.
Sewing machine oil works great for unresponsive lube!!!
+1 i use that stuff on my bearings its cheap and really thin! ;D
Gun oil, fishing reel oil.
I have 2 different types of trumpet valve oil that work wonderfully as well. You can pick up a pretty big bottle for about $6 at most any music store.
