To wash your car easily and more efficiently, without scrubbing, add a teaspoon of vegetable oil to the bucket before adding the water and car-washing soap. (Be sure to use soap designated for washing cars – household detergents can remove wax and mar the surface.) Soap's main job is to lubricate the cleaning process between the sponge or mitt and the painted surface; vegetable oil aids this process. To further prevent scratching, rinse often during the washing process.
