<human>:  How can I clean my car without using harsh chemicals?
<bot>: One option for cleaning your car without harsh chemicals is to use items you may already have in your home such as baking soda and vinegar. Mix baking soda and water to make a paste and apply it to your car's exterior. Rinse it off with a hose or cloth and then spray on a mixture of half vinegar and half warm water. Wipe the car surface off with a microfiber cloth. You may also want to use water and a car-specific soap for a deeper clean.
