How to stop helmet visor fogging

Fogging helmet visor wet rain work visorcat

Motorcycle helmet visor fogging is a major safety issue that doesn’t just occur in cold conditions, but also during rain in summer as well as winter.

Many modern motorcycle helmets have features that prevent fogging.

They include air vents, visors that prop open a couple of centimetres, nose/breath guards and anti-fog visors or inserts.

However, if your helmet doesn’t have these features, there are things you can do to make sure your visor view is always clear.

Blu-Tack props the visor open

The cheapest way to a clear visor is ventilation. Open any vents that are available. If that is not enough, you can prop open your visor slightly. It doesn’t have to be big gap. I use a piece of Blu-Tack on the bottom front aperture that prevents the visor from closing under wind pressure at highway speeds. I’ve also used bubble gum when I’ve been caught out in the rain without Blu-Tack. If your helmet has a chin spoiler, they are usually removable, so try taking it out for more air.

Visor inserts

Some motorcycle helmets come with anti-fog visor inserts when you buy them. If not, check your visor for little plastic “pins” on the inside or the helmet packaging for the words “Pinlock-ready”. Then you can fit a Pinlock insert. If not, you can also buy inserts that stick on. These inserts seal a bubble of air to keep the visor clear. Be careful to follow cleaning instructions and don’t use visor cleaners on them. Also, be aware that they can be ruined by dust, so keep the visor closed. These inserts can cost as much as a replacement visor, but are worth every cent.

Anti fogging masks

Face masks can also prevent fogging, although not all of them work well. In fact, some of them actually direct your breath straight up and can fog your glasses or the top of the visor! There are specific fog masks available that have a “breather” that points down and they fit closely across your nose and cheeks. Test it in store before buying. Put on the mask and your helmet, then breath heavily. I hope the shop staff don’t arrest you as some sort of perv!

Visor treatments

Keeping your visor clean will help prevent fog, especially if you use anti-fogging treatments and cleaners. There are many products available. They usually contain wax or silicon. You can also get anti-fog treatments for glasses that are sometimes cheaper than the same motorcycle-related product. In fact, it is important to also treat your glasses or sunglasses with the treatment. After all, there is no point in having a fog-free visor but fogged glasses. Make sure you apply them often.

Don’t forget to clean the outside of your visor. Usually fogging occurs when it is raining and there is no point keeping the inside fog free when the outside is covered in rain and road grease. There are a lot of silicone-based helmet visor and car windscreen cleaners that help rain bead off. Once again, car products are often cheaper than motorcycle products. I like the wipes because you can take one with you in a plastic sandwich bag in your pocket to re-apply on the run. They can also be used on your bike’s windscreen, if you have one. You should also periodically turning your head slightly to the left and right while keeping your eyes on the road to help the rain bead off the centre of your visor.

  • Do you have any other tips for anti-fogging your visor? Leave your comments below.

  1. Good article, think that covers about all of it. Removing your head to let the wind blow the visor clear, important to tell new riders to keep eyes front while doing that.

  2. You show pictures of Rain-X when writing about keeping the outside of the visor clean, but the Rain-X instructions are quite explicit about not using on plastics. I find Plexus very good, and it’s specifically made for plastics – I make sure to wash off dust and dead bodies with water before using any other cleaner.

  3. I like the neoprene masks that velcro to the inside of a helmet, respro Foggy Mask being the best one I’ve found, oxford do one as well but it’s pricier and not as good. Best in combination with a pinlock visor insert, they work great most of the time but moist breath makes everything damp around it on a long ride and glasses still fog, so the combination of visor and mask are made of win.

  4. In a pinch you can use dishwashing liquid as an antifog coating inside the visor. The thicker and goopier the dishwashing liquid the better. I suspect most of the antifog goops are some sort of condensed detergent anyway. All you are doing is modifying the surface tension between the water vapour and visor.
    Dishwashing liquid is a lot cheaper and found under most kitchen sinks.
    As a side benefit your visor might smell lemon-fresh.

    1. For what its worth, products such as Rain X and many dish-washing soaps are actually incompatible with poly-carbonate. They cause crystallization of the plastic which makes the plastic incredibly brittle.

      A fast version of this process can be seen by taking some expended glow sticks and popping them into a shatter proof poly-carbonate bottle, after about a week the bottle should shatter like glass when dropped.

      Anything with esters in it is a strict no.

  5. Mister _T is correct with the Dishwashing liquid .

    And when you home ,how easy to wash bugs and road grime off …..just add water 🙁

  6. Pinlock is the way to go, it really works. I’ve tried everything over many years but pinlock is the only one that really works. How tested? A 16000 km ride from Arizona to Anchorage and back in July. A few rainy foggy days that were a nightmare for my mate.

    1. I have a shoie neotec 2 so does my wife and one of my friends and we are all having problems with the visor fogging even though we have the pinlock evo fitted. Any suggestion on how to stop this

  7. With most of the modern helmets these days pinlocks do the job really well but in the days before that invention we used to simply use a bit of hard laundry soap or keep a bar of motel soap in a jacket pocket.
    Clean & dry the inside of the visor then just use the piece of soap and draw a few crosses on the inside. Then lightly polish the soap with a fine clean cloth , you don’t want to remove the soap just for it to be clear.
    Cheap, and very effective.

  8. Forget all those tips – we all know none of them fix the problem. I now actually enjoy riding in the rain looking out at all that wild weather through a perfectly clear visor – and perfectly clear specs. I close all the vents and exhale all my air through a 100mm long tube with an ID of 6mm and 2mm thick wall. I have a very small funnel with an ID of 4mm into one end of the tube and fashioned to fit my lips. at the other end I have a 3mm hole drilled horizontally through the tube in case the end of the tube happens to touch against something. I happen to have a chin spoiler in my flip up helmet so the tube sits comfortably inside my helmet with the end protruding such that I can easily position it between my lips when needed. I have ridden with ease for 250km with it in my mouth the whole time, breathing in through the nose and out through the tube. When the traffic was pulling over with their hazards going, I was sailing past, semi-trailers and all. I humbly accept all your grateful thanks in advance.
