EK USA, Cat Crap Multi-Use Anti-Fog Spray, for any Optics, Coatings, Eyeglass Lens Cleaner, Spray On - 1 Ounce Bottle

I'll be honest I think my 14 yr old son ordered this brand just because of the name! Thank goodness it works well too! I am so tired of buying expensive goggles just to hear that they fog up all the time. I haven't heard any complaining about foggy goggles since we got the cat crap! I actually used it on a pair of my old goggles and I am very impressed. After only 1 application there was a huge improvement a few more and no more fogging. I think we will always keep a bottle of this stuff around since we are a family of swimmers. Instructions were easy and simple. I could even understand them and that is saying a lot! spray some on and wipe dry. I understand that the 1-5 star rating is to help both buyers and sellers. Here is a breakdown of how my 1-5 ratings are determined: 5-star rating that means that I truly love that product and it has features that put it above and beyond what would normally be expected, and it is something that “wowed” me and I am truly glad I purchased it and would purchase it again. Also I recommend it to everyone and anyone! 4-star ratings are items that do exactly as would be expected of the item, is of very good quality, but does not stand out significantly in any way unless I specifically state why it stands out. But all in all, this item is a solid item and is still highly recommended. It just didn’t have the wow factor that my 5 star ratings would have had. 3-star ratings are given on items because my feeling about the product is neutral. I do not consider it a negative, but it just did not wow me, or there is nothing of great significance. 1 or 2-star ratings are rarely given unless the item is completely worthless and not worth the money, and I am only giving that rating as a warning to others. Some items have received lower ratings because of the way they were made or put together, and it is getting that review because of the quality of the item, which is specifically described in my review. It has to be pretty bad to get these ratings from me!

Thought this would help with all the mask wearing this winter, but it didn't really help much. Maybe the liquid version just doesn't apply as readily as the solid version. This spray just drips all over your glasses, then I think you end up wiping it off no matter what - either you use a cloth to apply it, which soaks it up, or you carefully try to spread it around while wet, but then it dries and there's all this residue obscuring your vision, so you wipe with a cloth and I think it takes the product right off. I mean it didn't do nothing but it didn't do what I wanted either.

This isn't to knock the product too much - my use of this is probably really extreme on the spectrum of applications - but I was not able to prevent my glasses from fogging in ski goggles while fat biking in sub-freezing weather for more than about 30 minutes. In every other aspect of this stuff's description - cleaning, not fogging as much going into warm places from cold places, etc. - it really works very well. I was simply hoping it would make fat-biking in really cold weather more comfortable by keeping the glasses clear in ski goggles, but it was not to be. I probably won't buy it again - not because it's bad or because it's a total failure (It's the best I've tried), but because I really hope to find something that can help keep glasses clear while in ski goggles!

I use this on the inside and outside of my face shield when turning wood, as well as on both sides of my glasses. As southern California is not a high humidity area, I can't speak to the anti-fog issue, but is does significantly reduce static cling of wood dust. I wish it would spray a cone of product rather than dribbles. Other than that, I am going to be using this product.

I used the spray version of Cat Crap after it was recommended by a medical worker. This product did not work for me at all. After proper application my glasses still fogged with a mask. They fogged walking out of air conditioning into the outdoors in a humid environment. This happened even right after application. This product was a waste of money and I don't recommend anyone buy it. The cream version may be better I just have no experience with it.

This product is only good as a cleaner. I always rub this product on my glasses and keep it on for, at least, 1 minute before rubbing/cleaning it off with a clean microfiber towel. I was outdoors in 52 deg F weather and sweating from a run. Yet, my glasses fogged up. I was indoors doing house chores and once again fogged up. Worthless product!

No problems. Use a light spray and it wipes off easly. I use it on a pistol optic It's perfect.

As a paraprofessional in an elementary school, I am in close contact with children. During this pandemic, I have to wear a mask and eye protection. I use this to keep my safety glasses from fogging up. There is a little fog here and there, but it does keep help. I keep this bottle at school and have shared with a couple of other teachers.

Holt euch lieber den Cat Balm!

Great product and it really does work, just spray on the lens and wipe and that's it all done. No more foggy glasses when you come in from outside or opening the oven door. I would give it a ten star.

The anti fog qualities last for maybe 2 hours max after application. Quite a waste of a product - buffing with liquid detergent gives longer lasting anti-fog.

Bought this for my ski goggles after I accidentally wiped the factory anti-fog film off. Sprayed this on and did not buff it, just wiped it around. Worked great! Have had no fog ups, just like the factory film. And shipping was right on time.

The product works exactly as described, no fog and lens looks very clear. But the spray bottle dosent work, i have to open the bottle and use like a dropper. The spray mist dosent come out. Looks like a defective piece. Very dissatisfied with the quality of the bottle used.
