Assuming you would like tips on how to clean road grime off your car:
Road grime is tough to get off and if not cleaned regularly, can permanently damage your paint job. To avoid this, it is important to remove road grime as soon as possible after driving. Here are a few tips on how to do so:
1) Use a garden hose to rinse the affected areas. Be sure to use a soft spray setting and hold the nozzle at least 12 inches away from the surface of your car.
2) Apply a generous amount of car soap or all-purpose cleaner to a sponge or washcloth. Rub the cloth over the dirty areas in a circular motion until you see the grime start to lift. Rinse the area with your hose and repeat if necessary.
3) For tougher spots, make a paste out of baking soda and water. Apply it to the area with an old toothbrush and scrub in small circles until you see results. Rinse thoroughly with your hose when finished.
4) If you have access to a power washer, this can also be used to remove road grime from your car’s surface. Be sure to use a low pressure setting and hold the nozzle at least 12 inches away from the surface while washing.
