You mix KLEEN GREEN GOLD with distilled or treated (reverse osmosis ) water in varying dilutions for different levels of cleaning situations. For DIRTY PIPES, mix 1 part KGG with 3 parts water and soak your piece for about an hour and then rinse clean. You can watch the gunk melt right before your eyes and leave a sparkling clean piece. For some applications, you may want to recycle an old spray bottle for your 3:1 mixture and spray those hard to reach parts. Go to the website for some convenient “how to” videos.
