Personally I only like the "old cymbal" look if its a nice even patina. My Formula 602's do not get cleaned. I clean my other Paiste's with Paiste Cymbal Cleaner. It works the best on Paiste cymbals in my experience. Then you can apply the Paiste Protector to keep it looking that way or it will just oxidize again.
You can try various waxes also to keep the shine. I have tried clear and paste type waxes and nothing works as good as the Paiste Protector for me.
