My protective goggles would fog whenever I used them with a dust mask. My breath would sneak through the gap at the bridge of my nose, condense on the goggle lenses and make it impossible to see. Then I remembered a trick that I’d learned about shaving at the bathroom mirror. I rubbed the inside of the lenses with a little soap and water (mostly soap), and the problem cleared right up.
