The cleaner works well to maintain the look, if you use it regularly from the start. It does not necessarily remove an old patina or deep stains, but does a great job of refreshing the surface of a cymbal from time to time.
I will buy the cleaner again for the cymbals i have where the fresh look is important.
The gloves that comes with it are nice!
I did not find the protection very useful.
Its a liquid blend of some waxes and stuff. The idea is nice, but in practice it dries a bit uneven, and leaves a thin layer that makes the cymbal look less pleasant again. Kind of nerfs the job that the cleaner just did.
