Muc Off Premium Anti-Fog Treatment, 32 Milliliters - Long-Lasting, Intensive Anti-Mist Spray - Suitable for Helmet Visors, Goggles and Glasses, Silver

I applied the Muc Off on my eyeglasses the night before in preparation for an enduro motorcycle ride (45 miles in the woods). Weather conditions were very good 7-75 degrees, , but typically when I wear my Rx glasses they fog badly after I am perspiring, due to vapor on the glasses (polycarbonate lenses).My glasses stayed completely fog free for the entire ride. Even when I took off my glasses occasionally when stopped, they did not fog instantly per usual. They remained clear. Excellent.I'll need to test further in cooler temperatures.

I use this spray to keep my Bauer bubble protector from fogging when playing ice hockey. Works better than other sprays I’ve used.

It works flawlessly for the first 2-3 split pea soup fogging the inside of your helmet like rides but then the effect dissipates quickly. On my morning commutes, I have been fogging my visor with the unusually cold weather but this resolved that completely. Unfortunately , it does require reapplication twice a week which deteriorates from the benefits. If you have a helmet that doesn't have a pinlock available and don't want to risk a cheap plastic sticker that will only last a season at best, this is the best option I have found so far, although a bit pricey.It can also be used in a car and lasts much longer but but I don't think it is worth the expense for that. (I was desperate and on a work trip where it was too cold for the vehicle to defog in the heated mode.)

Works as a good cleaner, but not great for fog. Had to stop and get a bottle of RainX Helmet anti fog.

I must be using it wrong because my helmet fogs like crazy every morning and I put it on every morning.

Works, but doesn't last. Annoying reapplying before and after work

Good

Riding my motorcycle in the morning there is so much condensation build up on the inside of my helmet. This product felt like I got pair of glasses I didn’t know I needed. I put this stuff on the inside of my helmet visor as well as my eye glasses. It creates a blurred effect which is safer than white out fog. It works so well I consistently apply it to anything I can. Definitely recommend!
