De-misting your windscreen with cat litter and an old sock
Indoor condensation in winter can impede visibility by fogging up windows. One clever solution is to use cat litter, which is rich in moisture-absorbing silicate. Fill socks with litter, tie them up and place them discreetly in the car. In this way, internal moisture is absorbed, preventing fogging and making winter driving safer and more comfortable. An economical and practical tip for overcoming this weather challenge
