Most specialist car brushes are designed to minimize the risk of scratches and damage to your vehicle. However, if you don’t take care to rinse off the worst dirt and mud before you get brushing, or you find yourself with tough, stiff bristles, then there still is a chance you can end up with some scratches. Instead, opt for soft or medium bristles – and try to give your car a good rinse first – to avoid the risk of abrasive bits of road debris being scratched across your vehicle.
