Washing your car by hand can be a relaxing and satisfying activity. Washing your own car will save you the money that would otherwise be spent paying for a car wash, and allows you to give extra attention to especially dirty areas of your vehicle. Commercial car washes use abrasive materials that may scratch or damage your car’s paint, so washing your own car by hand will allow you to keep the vehicle and paint job in pristine condition. To wash your own car by hand, you’ll need a flat, shady patch of concrete, and access to plenty of water and a hose. You’ll need to wash your entire car in one session, which usually takes an hour or two depending on the size of your vehicle and how dirty it is.
