Replying to Do you wipe your lens when they are dry or just not at all?

Ook so i have new goggles (spry soilders) and they fogged up imensley and i wiped the inside with some dry cotton. while skiing so yes they were wettish. i wiped the entire thing. i have heard of smuging of anti fog  coating. when i got home i  notice small smudges (verry verry small). When they were dry i meticulously used a goggle wipe to wipe them gentely and the smudges disapeered so i wonder if i wiped the entire anti fog coating of or they are fine. they seem fine. but i have yet to use them skiing again yet.
pleas help me out
