Re: Problem with cleaning a barlow

The TeleVue site offers the definitive answer.
In particular, note the suggestion of "fogging" with breath after use of the alcohol (or other solvent). I have found this to be THE finishing touch on any optical glass I find in need of attention.
It works extremely well.
I wholeheartedly agree, fogging with the breath and wipe off gently with a lint free lens tissue will remove nearly 100% of residue from cleaning fluids. Even Purosol will leave a residue, it's harder to see but it's there but your breath fog will remove it as well. And, as a last resort, for those pesky stubborn spots that just won't lift off....human spit on the end of a clean finger rubbed gently on the spot and 9X out of 10 the spots gone. Then clean that spot again with cleaning fluid followed by breath fog.
