As the cool morning commutes are getting more frequent, I start fogging my lenses at stoplights. I've used Cat Crap for a couple years, it's better than nothing, but I still fog over when I stop at lights: EK Ekcessories Cat Crap Anti-Fog Lens Cleaner at REI.com

I've heard some people recommend Rain-X:
Rain-X® 2-in-1 Glass Cleaner with Rain Repellent - Rain-X

Please let me know if you have used both and can offer pros and cons. Or is there something better than these two?

Related question, best sunglasses for airflow to minimize fogging in the first place? I've used a lot of different styles of glasses. Currently I have Tifosi wrapped sun glasses. I've used less wrapped lenses (aviators) and it helps with fogging, but if you're going fast down a hill, the wind comes in the sides of the lenses and can cause watering eyes.

Thanks in advance for your help!

I don't wear sunglasses, but I wear glasses. Luckily, fashion has brought large lenses back in. I chose large lenses with plastic frames. Plastic is safer in case of a facial crash. I just made sure the lenses are both wide left-right and tall top-bottom. They keep the wind out of my eyes, and I'm very vulnerable to wind. My old small lenses seemed to direct wind into my eyes, compared with wearing nothing.

The Cat Crap gets good reviews on he site you linked. There is one bad review, but it's probably an aberration; maybe the guy trapped dust unknowingly between his chamois and the lenses. Never heard of Cat Crap. Must try it!

I'm sure the scratched lenses happened because the user didn't clean the lenses first, or didn't use a clean chamois. I have the small tub of thick Cat Crap (apply it with your finger, rubbing around the lenses, let dry, and wipe clean), I haven't tried the spray version, I think the spray would easier to apply. Cap Crap is good, I'm just always looking for better (character-flaw).

Shaving cream works just as well, just use the part leftover on your hands after you scrub it into the area to be shaved, applying to glasses and wiping off without rinsing. It wears off but once a week seems to do it and no added cost or special shopping or extra can of gunk to find.

I put Rain-X on my glasses (cheap, plastic, slight tint) and it didn't seem to reduce the fogging (I rode through very thick mist yesterday morning), it may be better when it is actually raining and the water beads off.

There are two different Rain-X products. One is a water beader and the other is an anti-fog. As I understand it, neither are recommended on plastic lenses. I have a bottle of Rain-X anti-fog that I use on cheap sunglasses. I would not risk my expensive prescription glasses. No anti-fog product is going to give you vision as crisp and clear as untreated lenses.

I've tried Rain-X on my Rx lenses, not for fog which was never a problem, but to prevent droplets from forming. It helped a bit, but destroyed the coating so I gave up. Now when it rains, I'll get rid of the glasses, and accept soft focus vision. I can't read signs, but can recognize anything I need to worry about.

I came to this approach after broadsiding a slate gray van that I mistook for shadow because of the glare of oncoming lights through rain spotted lenses.

I just hd a non coated set of glasses made and may give Rain-X another shot when it starts getting dark earlier.

Once i get moving the lenses usually de-fog, however i am open to a new goggle purchase for the upcoming cold season.

I think something with a vertical strap might be good, to keep the back of the strap falling down when i put my headliner on..... any ideas?

Take a microfiber cleaning cloth, cut it in fourths.

Put a few drops of liquid dish soap or non-conditioning shampoo in a sink, fill with warm water.

Soak the cloths, let them dry.

Carry them in your jersey pocket. That's just enough detergent residue to cut water surface tension without leaving suds, so they'll de-fog your glasses while cleaning them, and leave just enough soap that rain doesn't bead up, it just washes down in a thin film.

I have a stack of them that I do up every month or so during Seattle's rainy season.
