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

It’s a little bottle. It works good on helmet face shields. My son and fiends race dirt go carts at Perris flat track in perris ca at night. It works but a little expensive for that size bottle. Use it sparingly

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.

It works fairly well but doesn’t last. I don’t really might having to reapplying when needed since I know nothing works long term unless you have pin lock visors. This works well enough for the colder months. It’s quick to apply and will last a few days to a week depending on usage. It does wear off if you clean your visor though.

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

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

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

Good
