2. Wash your car
Keeping your car clean is one of the basic car maintenance procedures. Washing it outside and inside should be regular and it depends in most cases on the climate and season. In winter, you need to wash it more often while in summer it should be cleaned one time per month. If you are not cleaning your car from dirt, mud, snow, salt, acid rain, the paint on your vehicle will be damaged very quickly and it will be harder to sell it again. You can buy all the detergents in the auto service shop.
