After a little reading (very little) and some common sense, I decided to try out a little Anhydrous Lanolin for cork grease. Anyone else use some sort of this? It makes sense, in that there is no water in it(wax usually has some water in it), and no petrolium. I figure at worst I bought some high quality hand cream. lol Anyway, at 4oz for $7, it's alot cheaper than cork grease made of the same(and who knows what else), at about that same cost for 1oz. I like the idea of going back to basics with natural products. I mean, that before the industrial revolution there must have been some other product used besides petrol products and petrol based wax(which is all cheap cork wax is). True, before petroleum, sperm whale oil was the primary liquid fuel and mechanical lube around. I have no way of knowing if that was the case with woodwinds, maybe you do, but I'll give this a shot on a couple of clarinets I will be working on.
