Just some quick questions regarding cymbal care. I really like the sound of my cymbals right now, but as I look at them I noticed they have gathered grease from my hands over the years. I imagined that has dulled them some and taken away the brigthness, which I don't mind too much, but I am curuios to see what they would sound like cleaned. Questioned I have is if I cleaned them do you think that would change the sound at all, a little, or not even noticabley? Also, what would you recommend I use to clean them? I have the following) 14" Zildjian New Beat HH, 16" Amir Zildjian, 18" A Custom, 13" Paiste Splash, 20" Zildjian ride (no specific series from what I can tell, but kinda old). Thank you.
