These are the cleanest I've ever seen. And they've never been cleaned. But the previous owner did actually abuse these cymbals quite badly. According to the seller he "whipped them" after every performance. In fact he actually "whipped them done".
"MY SLATER WHITE GLOVED ALL OF HIS DRUMS AND CYMBALS AND WHIPPED THEM DONE AFTER EACH PERFORMANCE."
"His Slater" was clearly guilty of cymbal abuse in the 1st degree.
