The BEST cleaner in the market today. This extremely dirty cymbal was cleaned using Groove Juice. If you do a frequent cleaning you don't need to rub it as much as on the video.
How does the sponge not scratch up your cymbals? Got a pile of dirty cymbals I'm trying to clean up and your vid was extremely helpful except I don't know what to do about the scratching/how to buff it out or just not scratch up to begin with
