<human>:  How can I clean my car’s exterior without using water?
<bot>: You can use a microfiber cloth and a cleaning solution made specifically for car exteriors. Make sure to read the instructions on the bottle of the cleaning solution before using it on your car. Apply a small amount of the solution to the microfiber cloth and gently scrub the surface of the car. Make sure to keep the cloth moist while working and avoid letting it dry on the car's surface. Once you have finished the scrubbing, use a clean microfiber cloth to wipe the surface dry.
