Foggy glasses seem to be a constant battle for mountain bikers, whether you’re on a cold winter ride in Colorado or hot, humid ride in Florida.  If you struggle with keeping your lenses clear try one of these three techniques!

#1 – Plain white toothpaste.  You will want to avoid any minty toothpastes with flakes or other special characteristics.  This method is very simple.  First, wet the lenses and apply a small amount of toothpaste on both the inside and outside.  Rub the toothpaste in thoroughly until the whole lenses have been covered and scrubbed.  To finish, simply rinse off the toothpaste and let air dry.  I like this method because it works pretty well and almost everyone has some plain toothpaste lying around the house somewhere.

#2 – Foam shaving cream.  Again, with this method you want to avoid gels or other special products.  Plain white foamy shaving cream works best for this project.  The method is virtually the same as the toothpaste.  Wet the lenses, apply the shaving cream and rub in thoroughly, rinse, and let air dry.  I like this method over the toothpaste because it seems to last slightly longer.

#3 – Sports anti-fog cream.  This method is by far my favorite as I have found it works the best.  I picked this up from some racquetball buddies who use this on the court because foggy glasses lenses are a major issue there as well.  There are a lot of companies that make a similar product and you can find something easily online or at almost any racquet sports shop.  I like this method because the cream comes in a small tin that can easily be stored in the car, bike toolbox, or pack, and can be applied easily on the fly.  Simply apply the cream to your fingers, rub on the lenses, and wipe clear for a nice, clear view.  Although most people don’t have this around the house like toothpaste or shaving cream I think it is well worth picking up a tin.  They are inexpensive and work extremely well.  Check out Z-Clear or my personal favorite, Cat Crap.

    Great info.
    Will these work with prescription glasses? I’ve read the 3rd one does not if the lenses have an anti-reflective coating. Any idea?

    Also, I seriously hope there’s a joke behind the horrible wanna-be-sweatbox-mousey-voice-spin-class music in yer vids.

      Have care with lenses that have a coating on them.. especially with tooth paste.. (it is an abrasive compound) it will remove your nice expensive finish.. shaving cream or dishwashing liquid would be my call.’

    I should add that – the reason that soap works (shaving cream/dishwashing liquid) is that they are hydrophilic.. that means they absorb moisture.. By absorbing the moisture that would normally bead up on the inside of your lens causing “a fog like finish” it spreads the moisture out across the entire lens surface. In essence it dilutes the detergent.. this is why the finish “wears off” you literally dilute it and it runs off the lens. Take a tissue that has had dishwashing liquid dried on it in a Ziploc bag.. if you lens starts fogging again, just wipe the inside with the cloth/tissue.

      Paper products will scratch plastic lenses. If you use a tissue with the soap for application, use a cloth to wipe it clean.

    Had the opportunity to try the shaving cream today and it worked wonders. Great advice … thanks.

    Thanks Colton and others for the discussion. I wear prescription glasses with a UV protective coating while riding. All comments were very helpful. One other thing to be careful of. If you spend much time camping with fires and you also wear prescription glasses with any coating, be super careful around the fire. I have more than once in my life ruined my glasses by getting my face and glasses into the heat of the fire too much while tending the fire or cooking on the fire. The heat will crack the coating and your lenses will looked all scratched up upon close inspection. This will be most noticeable and problematic in lights and sunlight.
