What mechanical methods can I use to prevent goggles from fogging. Can't use batteries or chemicals.?

Answer 1

for diving there is the full proof method of rubbing your spit on the glass - spit in and rub it then wash once and dive. (it works i tried)
try it for air it might work too. if not try some oil - it is my hunch that the water won't stick, it is said that wd40 will clear your mirror this way. i tried it once but it left the mirror a bit unclear.

Answer 2

observe: by no ability wipe interior the goggles 'cos the anti-fog fabric would be bumped off. to acquire the optimum earnings, save lenses unfastened from airborne dirt and airborne dirt and dust and grease. After each use, wash your goggle gently in sparkling chilly water. do no longer wipe or rub the interior the lens of the goggle. Use anti-fog drops including "Speedo® Anti-fog" drops to lengthen the existence of the fog resistance. i've got heard combination of glycerine and diluted dishwashing liquid will artwork as an anti-fog fabric ,too.

Answer 3

Use a blow torch......

On a recent trip to Cozumel, MX, I had a new pair of goggles and they kept fogging up on the dive. The dive master took a blow torch to the glass for a few seconds and then they worked like a charm!

Answer 4

Assuming they are not for under water. And they are plastic. I would drill small holes in them. Close to the frames, this will allow air flow and evap fog.

Answer 5

Might sound daft, but dropping them in water??? It certainly works in the pool! Got to be worth a try.

Answer 6

in NASCAR they take and rub a small amount of Dawn on the lenses until it dries clear. Do Not Rinse them off!

Answer 7

A long tube to blow 'cool' air across the glass with your mouth could work.

Answer 8

You have a built in anti-fogging compound, it's called spit. Try it, it will work.
