Ballistol is really universally without question. I use the Ballistol Spray mainly for harp and Zaumzeugpflege. Simply spray on, let soak briefly and wipe with a cloth. Everything is smooth and clean. (Then again quickly over boots, rubber or leather, no matter.) Disassemble for between one must not even the leather stuff. Metal buckles are equal mitgepflegt. The leather gear sets then the way in winter not as fast mold on.
