Hi everyone. Just wanted to thank you all for your replies. very helpful. so I went to my camera shop, and got a microfiber cloth/solution kit, and was able to get the nasty streaks and fisheyes of the two affected lenses. It did take a little work, and after a while it finally came off, but totally worth the time. I was really concerned the "Zeiss" cloths did some coating damage. Needless to say I've tossed them. Wilt, it really surprises me that a reputable camera shop would sell those products, but they seem to be everywhere. You'd think that Zeiss would have contacted that devision selling them and put a stop to seeling them for camera care. The only reason I got them was because of some stubborn water spots/rings on a couple lenses. otherwise, it's just a microfiber cloth, or lens tissue, and Tiffen, or Kodak solution at most.
Again, I can't thank you all enough!:D
Shane

homemade "KISS" solution:

50% distilled water
50% isopropyl alcohol

add to small spray bottle, shake and spray on clean microfiber cloth. for obvious reasons, do not spray directly on lens. will also clean monitors, eyeglasses, TVs, etc.

Dishwasher with spot free detergent.

I use a rocket blower and keep Zeiss lens cleaning wipes handy. The microfiber wipes concern me because they do hold on to the dirt.

100% agree. The iPA can be bought cheaply from Amazon.

Hollis has it right, but there's no need for the distilled water.

91% Isopropyl alcohol is the "go-to" stuff to clean glass surfaces. It also will not damage electronics (e.g. contacts, etc) and is what I use to clean flux and similar off very delicate surface-mount boards when reworking them, as a flush to drive water out of anything that gets wet that shouldn't and similar. Beware that it is flammable, including the vapors and evaporates quickly; for a number of years it was fairly hard to get and you sometimes had to ask for it because crack heads were using cotton balls soaked in it and lit as a heat source (yeah, really) but the last 5ish years it has shown back up out in the open, even at places like WalMart in their pharmacy area.

It's inexpensive and is the "right stuff." Put the alcohol on the cloth, not directly on the lens. That and a microfiber cloth or lens tissue paper (made specifically to clean lenses) will do the job for smudges and such. Just always be careful not to grind anything hard (e.g. sand, etc) into the glass surfaces. That's the risk with microfiber cloths; they pick up and hold things, and if it's grit and you rub it on the surface, well.... I keep a small bottle of 91 Isopropyl in my day bag and a few new, in-package microfiber cloths "just in case."

BTW it works really well on your LCD computer monitor too and is safe there as well.

As stated in post #16, a good squeeze-bulb blower and possibly a very soft brush are very important tools for the first stages of cleaning a lens. ALL particulate matter should be removed before doing any wiping if at all possible.

If you cannot remove particulate matter with a blower or a brush, use VERY LIGHT strokes with a dampened lens tissue (or a CLEAN microfiber cloth). This means that the only pressure between the tissue and the glass is due to the slight stiffness of the tissue and not your fingers pushing it onto the glass.

Seriously, I have been cleaning lenses with breath-fog and a T-shirt for 40 years. If they get stubborn fingerprints (or noseprints), I use any soft-cloth and a dab of Windex or 1:8 vinegar water. I have yet to scratch a lens.

Hollis has it right, but there's no need for the distilled water.

It depends just on what you're cleaning. Yes, it's often best to use it neat when you're trying to remove water or you're cleaning off oily stuff. But lenses are often contaminated with inorganic, polar, stuff - like salt. For that you really want something more polar than the neat alcohol, which is why I use a diluted for for cleaning lenses.

For preparing arrows for fletching I'll use it neat.

Yep can get boxes of the Zeiss wipe on the cheap in pharmacy are of Walmart were reading glasses and contact lens care products are sold. Keep a handful in you camera bag, vehicle, work bench....etc.

If an emergency, you can also use them to clean wounds...yes it will hurt like hell.
