Fog-Proof Your Windows in 30 Seconds Using Shaving Cream

Anti-fogging treatments save time in getting out of your driveway on rainy days when condensation forms on the inside of your windshield.

It only takes 30 seconds to do it with shaving cream.
 
Yes. Shaving cream.
 
  • Get two dry towels
  • Spray shaving cream on the towel
  • Spread over the inside of the windshield
  • Wipe clean with the second dry towel
 
That's it! How does this work?
 
After you’ve wiped off the shaving cream, a layer of residue is left behind. This residue contains detergents that lower the surface tension of water. Without surface tension, any water condensing on the glass cannot form into droplets.
 
It is these tiny droplets that cause fog to have an opaque white appearance. They act like curved lenses, scattering light in a thousand directions after it  hits them.
 
When the surface tension is broken by shaving cream residue, condensed water forms into a flat sheet of water, which is as see-through as the windshield glass itself.
 
Anti-fogging treatments were first developed by NASA in the 1960s to prevent astronauts’ helmet visors from fogging up during spacewalks. Little did they know, the answer was in an inexpensive can of shaving cream.
