Commuting - Will RainX prevent my glasses from fogging up?

My breath fogs up my glasses when I wear my balaclava and I was wondering if I treated them with RainX (or other similar product) if that would at least minimize the fogging.

suggestions?
solutions?

It depends on which RainX product you are referring to. The company makes several products under the name RainX including an anti-fog treatment.

See their website here and click on the Products link then the Windshield Treatments link.

I thought about RainX too, but I'm not sure my plastic lenses will be ok.

Skiers have been using an anti-fog lens cleaner called Cat Crap on their goggles for years. I've never tried it, but have met many who swear by it. Since most goggles are poly, I can't imagine it would harm plastic lenses... www dot catcrap dot com

Don't know about that, but another thing to try is to insert a vapor block. PSolarX has one that they sell for $5, but I googled around and found that it's just a hunk of foam cut to fill in the gap formed when the fabric stretches straight from your nose to your cheek. I made one in about 15 minutes (took a couple of tries) and taped it inside the balaclava with carpet tape. Stops most of the vapor.

Neat. Will catcrap make rain vision easier, too?

You can wear vented ski gogles over your glasses to prevent fogging.
To improve rain vision buy/cobble a large visor for your helmet.

Enjoy

I've tried both RainX and Cat Crap with little success. What has been working for me, even in this cold weather, is a new nanotech product called Clarity Fog Eliminator.

Applications, with a dry Clarity cloth on clean glasses, lasts about a week.

All great suggestions. Thanks. I was able to get my hands on a surgical mask here at work and I took out the metal nose piece and inserted it into the seam over the nose of my balaclava. That didn't eliminate the fogging but it did help and it was free. I might try the surgical mask itself.

People use Rain-x Anti-Fog (I recall it being Fog-X when I was a kid) on the insides of motorcycle helmets which are plastic without any problems, so glasses should be fine.

I thought about RainX too, but I'm not sure my plastic lenses will be ok.

If the lens are prescription. call the eye Dr. Otherwise, try the RainX or CatCr#p on the lower corner of the glasses.

Rain-X is not an anti-fog chemical. It is designed to make water droplets slide together in a sheeting action and blow off. I have used it on motorcycle helmet shields and it does NOTHING for anti-fogging, although it does make droplets blow off at 70MPH if you turn your head sideways.

I don't think it will be at all effective for bicycling purposes.

Well I always pedal @70mph no wonder RainX works for me! :roflmao:

You might try a scuba shop. They have products used for antifog while scuba diving and snorkeling. My wife and I have used some while snorkeling and it seems to work well. I assume it would work for our application too. Plus its cheap. I think I paid 2 or 3 bucks for what we got.

From the MSDS on Rain X The Invisible Windshield Wiper...

Its active ingredients are Silicone Oils, Siloxanes and Silicones, di-Me, hydroxy-terminated. These chemicals form Si-O-Si bonds with the surface of the windshield and have Methyl-terminated hydrophobic tail group which repels water. So, it should only work on true glass that is silica based, as the bond will only form with the Si-OH groups that are on the surface of the glass.

S-Si-O-Si-O-CH2-CH2-CH3 ---> Water
S-Si-O-Si-O-CH2-CH2-CH3

I have tried products similar to Rain-X. Oh yes the lenses (polycarbonate) don't fog. Instead I had a blurry film of water on the lenses. Might as well not wear lenses or goggles. Does not work in freezing conditions

I wouldn't recommend it. The teflon coating will cause water to bead even more but it's not clingy so it'll combine with other water to make large puddles.

Most glasses whether plastic or glass use coatings like anti-reflective, UV etc; Rain-X will remove those coatings! Read the bottle, it says not be used on paint or rubber or plastic...why? because it will remove any coatings, could damage paint, and eventually would make plastic dull out.

This is excellent information

I would be very careful about using RainX if your lenses have any type of anti-reflective coating that you're interested in keeping.

As a motorcyclist, I've always been told that Rain-X should NOT be used on helmet shields. I've never tried it because of the warnings. Lemon Pledge works pretty well with rain, but wouldn't be any help for fogging. I would recommend visiting an on-line motorcycle shop (Helmet Harbor, Dennis Kirk, etc.) to see what sort of products they have.

How about trying toothpaste or shaving cream?
