Most people are content to enjoy the beauty of snow from the comfort of their well-heated homes; others, however, find flying down snow-covered slopes on snowboards to be a thrill. Snowboarders wear goggles to protect their eyes from wind and falling snow as they speed downhill, but these goggles tend to fog up -- this can be a great annoyance as well as a hazard, as it is advantageous to be able to see the ground ahead when racing down a slope at 60 miles per hour. Defogging your goggles will keep them clear; a variety of household products work as defoggers.
Toothpaste is effective not only for cleaning your mask but also for preventing fogging. Use only regular, non-gel toothpaste works for this purpose. Squirt a drop of toothpaste into the inside of the mask and scrub it into the glass in a circular motion. Clean the mask with warm water to remove any film from the toothpaste.
Baby shampoo is soft and won't scratch your mask; it is also designed to be gentle, so unlike commercial, chemical-based defoggers, it will not burn your eyes. Rub a small amount of baby shampoo over the glass of the mask; then run water run over it to remove any excessive film. Glass forms condensation when exposed to sudden temperature changes, which accounts for the fogging; the baby shampoo prevents the condensation from sticking.
Hair conditioner is also known to work as a defogger. Conditioner has a number of ingredients including lubricants, moisturizers, oils, thermal protectors and preservatives that regular shampoo does not, and these help the conditioner to be an effective defogging agent. Spread a small amount of conditioner over your mask to prevent condensation; then, buff the glass with a soft rag until it becomes clear. A thin film will be left behind, which serves to repel the fog.
Defogging Fans and Heaters
Some snowboarders -- as well as participants in other mask-wearing sports such as paintball -- install extra equipment to their masks; these are often small, homemade fans or heaters. Such fans have small battery packs that mount to the side of the goggles with glue or a screw. The fans and heaters are then installed in the vents of the goggles and switched on for a short time when needed. These work much like the windshield defrost on automobiles; by changing the temperature of the glass they cause the condensation to evaporate.
