Keep the goggles vent foam clean
keeping the vent foam clean is important for proper air flow! The best way to keep your goggles clean is to remove the lens carefully and clean them by hand with warm soapy water, try to use a mild detergent if possible! The foam on your goggles is fragile so be careful not to put any tears in the foam, its also possible to pull away the foam from the frame and not notice the gap or hole. Carefully install your lens and inspect your goggles thoroughly for tears and such. Take care when removing and re-installing the lens because this is the most common time to damage the goggle! If any damage is detected, repair or replace at this time as needed! (for repair tips look up on my earlier reply under SPEEDSHIFTER) For all those with deep pockets or for those who can't find the time to do it right, just pull the lens and throw them in the washer with the rest of your gear, just don't forget the inspection after you re-install the lenses! Once the goggles are dry you can oil the vent foam for your next ride! Don't over oil this will just make a mess and if you get oil on the lens you will need to remove it, to clean it properly. Note: it is very difficult to install a lens without getting oil on it after the goggle vent foam has been oiled! Always install the lens before you oil the vent foam! I oil the vent foam by dipping a Q-tip into the oil, then I dab the Q-tip on the outside of the vent foam. Don't over oil, a small amount is all it takes! Just be sure all the vent foam is slightly moist with oil, any area that is not slightly moist will be an entrance for dust! (DO NOT OIL ANY OF THE FACE FOAM!!!) (TAKE CARE IN YOUR OIL SELECTION, I USE BABY OIL!) (CAUTION PERFUMED OILS MAY CAUSE YOU TO TEAR OR HAVE AN ALLERGIC REACTION!) GOOD LUCK!!! ;)
