Last week I cleaned up several newer Paistes -20" 602 Classic Medium Ride and an 18" 2002 Thin Crash, plus my Zildjian Custom A 14" Mastersound hats with some Paiste Cymbal cleaner. Worked well. I have some older Zildjians that do not have the brilliant finish and was going to Groove Juice 'em. I will likely try the Barkeeper's Friend SC based on your recommendation.I'm one of those people who can't stand grimy cymbals. Mine are polished and looking brand new.
I recently started using Barkeeper's Friend Soft Cleanser and I'm blown away by the results. I used to use Groove Juice for everything but my cymbals would tarnish fairly quickly after being cleaned. They look amazing weeks later after being cleaned with BKF. Highly recommended!
