Cars can get dirty very easily. Car exteriors seem to be magnets for dirt, road tar, tree sap, bird droppings and other contaminants. At the same time, vehicle interiors suffer from dirt, dust, pollen, moisture, spills, food particles, smoke and vinyl vapors that cause wear and tear, create unpleasant odors, and leave stains and deposits on interior surfaces and glass. Also, over time, both the outside and inside of a car can deteriorate from exposure to heat and ultraviolet rays from the sun.
The only way to combat these automotive enemies is regular cleaning and detailing, which makes a vehicle more attractive, extends its service life, and preserves more of its original value when it comes time to sell or trade. AAA recommends washing a car every one to three weeks and waxing it two to four times a year, depending on vehicle use, road conditions and weather.
