I break glass everyday? But I do clean it a lot! I have more glass than is necessary. I like it clean 4 sure. Baking SODA + WHITE VINAGAR + dish soap + warm H2O + (salt if you have grime) SHAKE it (wine stopper's for the opening's) I rise with clean RO water and I squeeze a CITRUS fruit of some kind. (they grow wild) I tried all the KIND U CAN BUY. My wife is a clean freak like me. Now I'm super cheap so what I say is kine preference? Ph is your friend! EVO is your FLAVOR MACHINE! Clean Glass = CIVILIZED Their R product's U can buy as well! EVO customer service cleaned my glass last time and was perfect like a bought one?
