Crazy John's makes three different products for drums, all of which have been developed specifically for resp. traditional cymbals, brilliant cymbals as well as drums and hardware.
These maintenance products are nothing short of superb. Combined with elbow grease, in the careful way, you can achieve very fine results.
Crazy John's Brilliant Cymbal Cleaner is intended for the maintenance of brilliant cymbals - ie cymbals without grooves that are polished from factory.
Apply Crazy John's Brilliant Cymbal Cleaner to the surface with a soft cloth.
Gently rub on the cymbal and get the detergent working quietly into the cymbal.
Next wipe the cymbal with a clean soft cloth and polish it up so that it is like new again (or as close as possible).
Remember! It is always a good idea to test the cleaner in a less visible place before you start with the entire surface.
