Muc-Off 214-1 Premium Anti-Fog Treatment, 32 Millilitres - Long-Lasting, Intensive Anti-Mist Spray - Suitable For Helmet Visors, Goggles And Glasses

Used it on my sunglasses, visor for my motorcycle helmet and goggles. Does perfectly. Just spray on and wipe for a few minutes, stopped my stuff from fogging up completely even with a mask on

works very well for a day or so, I used it for airsoft and paint ball, had to reapply after a day or so of usuage.the bottle lasts quite a while even with using it a lot.easy instructions to follow and fits in a pocket nicely

Great product

Not sure if this is dependant on your helmet, but I have an Icon Airframe. My journey involves a decent open ride, then into slow and start-stop traffic regardless of lane splitting/filtering. When I first got it I used Muc-Off's cleaning spray to make sure my visor was clean (that product is great btw), then I used this and the next day tried it out in the cold morning. It works for about 30 mins, but once I get into slow moving traffic it beings to fog up. Admittedly it's better than it used to be, it kinda forms droplets rather than fog, which is better but nonetheless still unwanted.I figured maybe I didn't apply enough. So again I cleaned it and this time I absolutely covered it in this stuff, no chance of missing any spots or having too thin of a layer. Still the same thing occurred. This is just my experience, who knows maybe you will get a better result with a different helmet (not that this should make a difference tbh...).TL;DR: Kind of works, not worth the premium price though, and certainly doesn't work for a full trip, never mind 'up to 4 days'. So its a 3/5 from me - Kind of works, not good enough for the price.

Works fantastic, a spray in some goggles and they stay mist free all swimming session.Easy to use, and very good value for money as this will last years

Good stuff

**Edited review**I have found it's best to spray the liquid into a tissue then very lightly apply it to the visor and wipe off any obvious Access well then it does actually work ok for a few days.So actually it's probably worth getting and trying just don't spray it on your itemJust no!Ok this stuff does stop my inner sun visor on my bike helmet from fogging up.But now It goes like a gooey substance on the inner visor which makes the vision worse than the fogging up.At first it seems ok but obviously the moisture in the air and from my breath reacts with the formula and it only gets worse the further you go.At least with fogging up it only happens when stationary and clears when moving.Not so with this liquid as I said it just gets worse as you ride.So I've washed it all off and binned the bottle a waste of a few quid but safer to waste it than to use IMO

Very good stuff to stop fogging on my airsoft eye protection. For best effect, spray on the night before and let it dry naturally. Good price and better than some other brands I have used.
