I have tried everything in my arsenal including bleach wire to all-purpose cleaners to purple power and the list goes on and I cannot get them totally clean every time I go back and wipe them down I still get black on the medium that I'm using. Washed as many as 3 consecutive times.
And yes I've even used Mckees rubber rejuvenator. What can I do to get them clean without any black residue coming off?!?
