Human: What is the best way to keep my car clean? Assistant: 
The best way to keep your car clean is to wash it regularly with a good quality car wash and wax. Make sure you use a gentle, biodegradable soap or detergent and rinse thoroughly after washing. Vacuum up any dirt and debris that has accumulated inside the car, and wipe down all interior surfaces with a damp cloth. For an extra shine, apply a coat of wax before drying the car off completely.
