EK USA, Cat Crap, Anti-Fog Lens Cleaner Balm, Safe on All Lenses, Eyeglasses, Goggles, and Camera Lenses - 0.5 Ounce

I got this as Rex Specs recommended it to clean their goggles, and I have a set for my service dog. This stuff is MAGIC. I swear. I got a preowned set of Rex Specs that were dirty and just needed to be cleaned up and this stuff was gentle on the lens and cleaned it to a shine. I keep forgetting to try it on my own glasses but I have no doubt this would work super well (better than that spray stuff) on them as well as scuba goggles too.

I have to wear safety glasses at work, which isn't a big deal. What became an issue though was due to going through the womanly change, I am perpetually hot, causing my safety glasses to fog up, which creates its own safety issue. I did some light research on finding a product that helps with my issue and this product came up numerous times, so I decided to try. I'm glad I did. It definitely helps keep my glasses fog free. Some days I do have to apply it 2 or 3 times in a shift, but most days, it is 1 time, if at all. A little bit goes a long way. I will be buying again in the future.

I purchased this for my hubby who is a welder and is forced to wear a welding hood and safety glasses in an overly hot humid shop. He also has to wear a thick long sleeve shirt, so not to burn himself while working with the lava hot metal. Oh and did I say we live about 1 mile from the Louisiana coast? It is humid here year round. Needless to say the safety glasses fog up and that can be a real safety issue when working with lava hot metal. The comically named Cat Crap works as it is advertised however it is not perfect. Hubby has recommended it to a couple of friends, since it is a lot better that the spray on stuff that is provided at work. However great it is, there was 1 occasion where it had been raining every day for about a week and the safety glasses did fog up. So I would have to say that it works great, but this stuff even has its limits. Cat Crap Anti-Fog EK Cat Crap Lens Cleaner

A friend recommended this as a possible solution to fogging. On my first time out using my goggles that fit over my glasses this is what I experienced. I was surprised on my 70 minute bike ride in low 20 degree temps on how clear my glasses were starting out. About 20 minutes into the ride I had to walk through a section of trail that had 8 inch drifting. No way to ride my fat tire bike through that. That is when the glasses began to fog. Once I started back riding again and getting past 5 mph, the glasses began to clear up. Never 100%, but enough to see. Still worked better than other things I have tried, but not worth the money in my opinion for how and why I use it. I will try it again to see what happens and update this review. The photo is at the end of my ride. UPDATE tried it three more times: 1. With different goggles (Bolle with better ventilation) wihen using a snow blower, still fogged. 2. Single coating using the Bolle goggles on a bike ride 8.3 avg mph. Anytime I slowed down they fogged. 3. Double coating on a bike ride 8.5 avg mph with a 10 mph wind out of the north. Better overall but when slow my glasses would fog, when moving into the wind they would clear the lenses. When going cross wind the lens downwind would fog, the other would clear. Ventilation in the googles is a factor. Wearing a full face balaclava is a factor when mouth is covered, but still glasses would fog when slow or stopped even when my mouth was not covered. Breathing though the balaclava causing warm moist breath being directed upward into the goggles would cause the glasses to fog..

I ordered this to use on my Eclipse Integra P100 respirator which fogs up within 5 mins of use. I live in the south, which is always pretty humid, especially in the summertime. After reading reviews and doing research, cat crap anti fog was recommended and vouched for to solve the problem. I applied per directions and immediately the mask fogged up to the point I couldn't see my stop cut line I was routing for my dado joint. Useless and waste of 10 bucks. The only reliable method of anti-fog is to heat the mask up with a hairdryer to the same temp as the heat radiated from your face (match the latent heat of vaporization). Effective but super annoying and hot in the summer. Wish cat crap worked as advertised so I wouldn't have to do this.

Indoor shooting ranges seem to conquer every “anti fog” lens but this stuff works like a charm even when I’m dropping tons of sweat.

Keeps glasses from fogging even while shooting

The Cat Crap paste simply did not work for me. I work in a meat processing plant where I am moving through rooms with varying temperatures from -25F to 100F. Add that everyone at the plant is required to wear a face mask due to the "Baloney Virus" henceforth "Blovid 19", the fogging issue with my prescription glasses and goggles is problematic. I used the product as directed, then tried several methods that weren't suggested and 1 or 2 that are downright unadvisable if not dangerous and the results were the same, still foggapalooza. I gave it 2 stars instead of 1 because I like the name and it shipped FAST, but for my application it was useless. At least the name got it half right.
