An automatic car wash is the most water- and energy-efficient way to wash a car, and it's especially useful in the harsh winter months. When roads are treated with rock salt to deice them, the mixture of melting snow and ice with the salt can cause rust on the undercarriage of your car. After a harsh storm, visit an automatic car wash and opt for the undercarriage cleaning along with a hot wax seal. This will wash away the salty mixture and create a barrier that will protect your car from further winter damage.
