4 Use potato juice to stop your windscreen freezing
Potato juice isn't exactly in high demand, you’re not likely to find it alongside orange, apple and pineapple juice at your local supermarket. But with a little foresight it might help you avoid frosted windscreens. This is another to apply the night before, so dig out some spuds (from your cupboards, not the neighbours allotment - unless they give you permission), slice one in half and rub the cut end directly onto your windscreen. If it starts to feel a little dry, carefully slice another layer of potato off to reveal more juice.
