On cleaning- google up "Moose Milk" and "Ballistol". It's water mixed with Balistol, which emulsifys. The water evaporates out of it and leaves the oil. I forget what property it has that neutralizes the sulfers and salts, but.... oh duh, I guess that's the water doing it's part.
Considering your target audience is scouts, they would probably benefit from knowing about all the uses for Ballistol anyhow.
