I am in need of first hand experienced based information on any after market anti-fog coatings or whipes that anyone has used and "KNOWS 100% for sure actually works. I have heard of products called "Scope Dope", "Cat Crap", and some new cloth wipes bt I think Nikon that all claim to prevent the lenses of scopes, binos, and glases from fogging up, but before I buy them I would like to know what any one here thinks of them if they used them.

I am asking because my breath fogging up my scope cost me a shot at a quite good 6x6 bull last time I elk hunted and i would like to avoid it hapening again.

Lastly, a guy working at my local Cabela's suggested I try Rain-X anti-fog on my scopes rear lens as he claims to have used it for years with out nay dammage to the lens coating and it works great, again according to him.

Thanks for your input on this.

birchwood casey sells an anti-fog scope cleaner; I used their wipes and they worked fine for a northern michigan hunt with light rain and snow.

I have a Bushnell 3200 elite scope on my rainny day rifle & it actually works. Leupold sells a set of anti fog lens covers for their semi current production. I would not use a OEM anti fog product on a good scope just too much to lose.

Use as directed.

Anyone who uses Rain-X on fine optics is nuts. It has chemicals that will remove most optical coatings.

You would be surprised how many times I've heard of folks using Rain-X. I wouldn't buy a used scope from that Cabelas salesmen.

Understand that while fogging can be reduced, you lose acuity. How much? Dunno.

Simple and effective is to use a film of glycerin soap on exposed lens surfaces. What may also work is to spread a drop of pharmacologically pure glycerin -- the working ingredient.

An easy way to test each product is to apply it to a spectacle lens, first one exterior surface, then both exterior surfaces of one of its lenses. Put in freezer for a while. Then put them on. Fog is NO PASS. Clear is PASS. Your untreated lens is your control. And you will not have harmed/affected your telescopic sight lens.

Hope this helps.
