I purchased the lens cleaning kit from Orion ~$16 a while back. It includes a small bottle of cleaning fluid, two packs of super soft lens tissue, soft brush and compressed air. You can get a 3 oz bottel of Zeiss cleaning fluid from <eagleoptics.com> for $4.95. I am not sure if these specialty fluids are better than what you can mix your self using distilled water+ ? I just feel safer that way. You may be able to find lens cleaning kits if you have a well stocked camera store near you. Most mail orerds operations have minimum shippping charge. It may be better for you to purhase it locally.
It's best to clean multi-coated optics as little as possible. I always cap my optics when I am not using them. A little dust does not hurt performance but spreading tiny abrasives around with tissues or cleaning cloth not desigened to do the job will.

One of the better articles that I have read can be found at this link-http://www.companyseven.com/library/clean.html I hope that I am not breaking any rules by doing this. In any case this article does in my opinion a very good job of telling you how to clean optics and what to use.

Seems to me that I read DO NOT USE the cloth that comes with binoculars on the optics here on CN. As I recall, the thread stated that such cloths were best limited to cleaning the body of the binoculars but NOT the optics. If, on the other hand, the package that the cloth was in is labeled, "Optics Cleaning Cloth", then it may be safe.
The link that Dan suggests is excellent. I would follow those instructions, especially with respect to any oil or grease that may be on the optics.
Good luck. Nick

I really sympathise with you in your predicament.
It sounds to me like it was a GREASY deposit causing the smudge in the first place , and you simply succeeded in removing some of the grease but not all of it , some of which is still forming the "streaks".
Not being an expert on either coatings or lens cleaning I am not prepared to put YOUR binocular objective AT RISK by advising anything -- but I know how to get rid of grease from glass surfaces -- I do it every day as part of my profession !
Have you considered asking Kevin at Big Binoculars ?
He will know more about the actual coatings and might even be able to advise you on the best course of action.
Just a thought --Kenny.

I'm DELIGHTED for you.
If you happened to read one of my posts on this topic on another CN forum a few weeks ago you would have found what you did is PRECISELY what I advised.
I did not exactly get "praised" for my suggestion -- but HEY -- I've been using ( and cleaning )binoculars for close on 40 years !
That must count for SOMETHING.
Enjoy your "crystal -clean" 20 x 80s :-)
Clear skies -- Kenny.

Dawn is effective and benign (it's what is used to clean wildlife coated from an oil spill). The only thing I'd add is to use distilled water.
I agree with Rusty - do not use spring or mineral water. They contain minerals which can leave residue. Distilled water is a 2:1 mixture of hydrogen and oxygen only. You should be able to get a bottle at a pharmacy.

We use distilled water in our steam iron at home. I get it at K/W Mart for ~0.69/Gallon. Never have to worry about steam vents clogging up. Remember to cap it after you are done to keep our airborne dust after you are done.....
I find it easier to buy specialty lens cleaning fluid from Orion or Zeiss for my optics. I use the $2.99 Walmart lens cleaner for my eye/sunglasses only. Save the $5 Zeiss fluid for my bino/scopes. I have no idea if the Zeiss is any better. Just make me feel safer using it..... I noticed the 3 oz. Zeiss bottle says: Especially formulated for Carl Zeiss Optical, by Nanofilm, Cleveland Ohio. It's a US product after all.
