Condensation is a common problem in old cars. It covers the windscreen and dangerously reduces the visibility. Here is a tip to avoid having clouded up windows in the morning.
You will need :
— An old sock
— cat litter (if possible with silica crystals)
How to do it ?
1. Fill you sock with cat litter up until the height of the heel.
2. Make a knot and place your sock in the car, onto the dashboard for example. Admittedly it is not very sexy…
The absorbent power of silica crystals should reduce the steam considerably.
