Muc-Off Premium Anti-Fog Treatment - Anti Fog Spray for Glasses, Goggles and Visors - Advanced Demisting and Moisture Absorption - 30ml

Good, works well

I purchased this primarily for use with a Ring doorbell that constantly steamed up Pro: * 32ml, I have found that due to the small area, I need to use only one spray; it Is more than enough. So, in theory, this should last quite a while. * It’s only been two days since I last used it, but we have had rain, sun and thunderstorms. These conditions are an issue, particularly if it becomes sunny as condensation builds up, this making motion detection useless and having to wipe down constantly. Since using this, I haven’t had to do either, and the image remains clean of debris and condensation is primarily purchased and what I wanted it to do. Con: * If you’re going to use it with a Ring, I thought it could spray and allow it to dry naturally, Don’t do this. I tried, and it left a red residue behind in some areas (although the liquid was clear). It took quite a few damp cloths cleaning and buffing to remove. Ensure when you spray, you immediately wipe. * Having read some of the reviews regarding smell, I can confirm it does have a scent. To me, it smells like boiled eggs, so not ideal if you intend to use it on glasses as you’ll be able to pick up on this. It isn’t an issue for me personally due to solely for outdoor use. My partner did use it on their glasses but found the scent disgusting and lingered; therefore, they had to use liquid detergent to remove it. Overall, I would recommend if you're using outside on a ring doorbell or similar on glasses, probably not so much due to the smell. I wouldn’t also say it’s worth the asking amount of £12+. Thankfully the price has dramatically decreased.

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

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.

This does work, looking at the reviews I was unsure and never usually get time to leave any reviews but cleaned my visor and screen on my motorbike and sprayed a small amount on kitchen roll and wiped it over until it dissapeared and I can’t get it to steam up so it’s brilliant, it does say on the back to re apply every 5 days or so with regular use so the negative reviews saying you have to reapply ignore as it states that, I think the little you will use it will last a year for a tenner so that’s good with me 👌

The google spray is value for money and it's easy to use.

**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 item Just 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

As an extremely busy nurse and someone who is short-sighted, I need my specs for work. Contact lenses dry my eyes out and cause my eyes to feel tired if I wear them for 13hr shifts. Usually, I put a mask on when I enter the hospital and straight away the ‘fun’ with fogging and de-fogging begins especially if it’s cold outside. A fellow colleague, who also wears glasses all day at work, told me about this when I walked in with partly fogged glasses. She couldn’t praise this product enough and I ordered one that very day. I tried it for the first time a couple of days ago and it was the first time ever since having to wear a mask that my glasses haven’t fogged up when I’m hot or enter a building!! Also, I didn’t have to apply it again for the whole day! Glasses can be cleaned as normal without compromising the anti-fog protection that Muc-off gives. When I used it for the first time, I sprayed my lenses on both sides and cleaned them. I repeated this step 3-4 times and that seemed to do the trick. Would one layer do the same job? Who knows? Also, it cleans my glasses very well. There was not a single smear or glare to be seen when I drive at night. If you’re a glasses wearer and your glasses fog up, this is a necessity.
