Baader Optical Wonder fluid

[Crusader]

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.

I use pure isopropyl to clean my eyepieces, but instead of Q-tips I use tightly rolled and twisted Kleenex white tissues that I snap in half leaving a soft, fuzzy end. Dip the snapped in half end in the isopropyl, clean the eyepiece then spin the tissue around and gently wipe the lens with the dry end - this absorbs the isopropyl and reduces the residue on the lens, except for a little around the edges, which doesn't matter.

I like the rolled and twisted tissue since you can't apply pressure to the optical surface even if you try - the tissue just bends.

i just use everyday cotton buds with alcohol, keep the liquid to a minimum though - don't drown it...wipe around - then hot breath followed by a wipe with a lens cloth (one from an optometrist )
