Do not mess with the wood outside wiping it with a paper towel or at most a wipe with Ballistol.

The metal, bronze wool, or very fine steel wool lubed with lots of Kroil Oil. Soak it with Kroil first, for days. The Japaneseicon rifles tolerate 0000 steel wool better than any I have tried it on. Go slow, light and keep it wet and wiped away frequently. Bonze wool is safer they say.
