These days, when you go in the car in the morning, the windows are all fogged up and you are wasting minutes to clear them before hiting the road.
However, this mist can be avoided: it is possible to prevent the fog, even with the changes of temperature and the humidity.
This man made a test: he tested 5 products that have the reputation of preventing windows from fogging.
He started by sticking tape into the driver's window to separate it into 5 sections, one for each test. He also had a pan of boiling water to cause fog inside.
He tested a commercial product (Rain-X), shaving foam, baby shampoo, a cut potato and hand disinfectant.
The result: only 2 products work perfectly, while the other 3 tests failed!
