Goggle AntiFog Tips
Cold weather = fogging up for your goggles/eyewear. The following are sugggested tips for dealing with fog prevention.
Do not overdress. Be warm, but not too warm. Exercise, skiing, or any movement generates heat and if sweat is forming on your forehead, your goggles fog up. Take off a few layers until you are comfortable.
Snow. If it is snowing and your goggles begin to fog, check to see if the snow has clogged the vents. If they are covered, the heat cannot escape so do your best to remove the snow.
If your goggles do fog, never wipe them clean. Doing this reduces its effectiveness. Anti-fog treated lenses will heal themselves given time.
Never clean your goggles with glass cleaner...that removes the anti-fog coating and only use anti-fog sprays or liquids on your goggles when the factory anti-fog coating has worn off or been removed.
For glasses wearers, try putting on the goggles before leaving the indoors since this will prevent the glasses from getting cold. If snow/water gets on your glasses/goggles, blot the water droplets dry with a soft cloth. Even remove them and set them foam side down on your leg so the moisture-laden air can dissipate and the no-fog coating absorb the remaining moisture. Do NOT use chemicals or detergents to clean lenses that have an anti-fog coating. Use a soft cloth (like a micro-fiber cloth) to wipe clean.
**Please note that some of our eyewear already has the anti-fog coating, see the descriptions to be sure. However, there is always a possibility that these goggles will still fog-up depending on the situations as said above. Extreme conditions can also affect the anti-fog.
We bikers do our thing in environments that cause our glasses to fog up from our warm breath. Such a darn thing to put up with, but can easily and inexpensively be cured.
Several anti-fog compounds are packaged and marketed expressly for this purpose. They cost quite a bit, some work great but others are a total failure. Virtually all of 'em have one common component that makes 'em work: glycerine.
Glycerine just happens to be a high-percentage ingredient in hand soap. The stuff marketed for women has a higher percentage than the other types. it has more glycerine in it. But most any soap works pretty good.
So, cut off a piece of hand soap, smear it on your previously cleaned eyeglasses, then, using a clean, cotton cloth, rub the streaked soap all over the lenses to where it's not visible any more. Works fine, lasts a long time and works better in my opinion than any of the stuff you pay a buck or more per half-ounce for.
Some soap brands/types tend to be better than others. Neutragena has about the highest glycerine content of any soap. It's a bit softer than most soaps, but rubbing your finger on it, then smearing it on your eyewear works fine. I take a chunk of it and put it in a clear,
plastic 35mm film can. Ivory soap and `Pure Pleasure' glycerine soap work very well.
