Baader Optical Wonder fluid
Has anyone used the Baader Optical wonder fluid and Micro Fiber cloth to clean their eyepieces? How does it perform? I'm struggling with streaks using Isopropyl alchohol and Q-tips to clean my Eps.
Also how does a single bottle last and does it have an expiry date? I'm thinking of order 2 bottles to save on shipping, but wouldn't want one to go to waste if they 'go bad' after some time.
