Hey man, I thought your cymbals were new??
Shouldn't 'spoil' per se, the only cymbals that might suffer 'damage' are some B8 cymbals and most Paistes (because of special lacquer/coating applied to prevent tarnish as B8 tarnishes way faster and more drastically than B20).
If your pies are new, a good wipe to remove dust and fingerprints after each gig/practice session should keep em looking new.
Just to be safe, you can try a little bit of the cleaner on a small spot on the underside of a cymbal.
Do you have the cream or the paste? Generally most cleaners are made of a mild abrasive which removes a microscopic amount of metal, so be careful when cleaning around the logos, if you want to preserve them.
