Goat Tuff Cleaning Concentrate is tough on dirt and grease, but easy on your carbon or aluminum arrow shaft. Made from a mix of organic, biodegradable ingredients, this cleaner is safe and easy to use. Just mix 2 ounces of concentrate with 14 ounces of water, moisten a towel, then wipe down the arrow shaft. Comes in a 2 ounce bottle. Mixing bottle and towel sold separately, or in the Goat Tuff Cleaner Kit.
