Your Car’s Exterior
Make sure you have a good quality car soap. Don’t have any on hand? Do NOT be tempted into using dishwashing liquid as car wash soap – it removes the wax from your finish! Make a quick run to the store for the real thing. It makes a difference! Use one bucket for the bulk of the car, and the second one just for those really grimy parts: wheels, tires, and the lower quarter of the vehicle.
Use a microfiber cloth with a good quality car polish to get those scratches off, and get that paint shining again. (note: Polish makes it pretty, wax keeps the finish protected)
