I’m just about to do a CCC to CIC retrofit and the ‘new’ screen had fine scratching on the AR coating. Rather than using any of the polishes mentioned in this thread, I used sunscreen. Yes, sunscreen as in what you apply to your skin to prevent sunburn. No hard rubbing or polishing required. Just smear the lotion over the screen and let sit for a while. The stuff dissolves the coating and just you just simply wipe away.
