I wear the AirOptix Colors. LOVE them, but they start feeling grainy after 10 or so days of wear. I was told that it is protein build up. I have bought up a good supply of OptiFree PureMoist but the Opti-Free SupraClens doesn't say to mix it with the PureMoist...but the OTHER 2 cleaning solutions they have. What will mix with the PureMoist...is there any that will?
