Write the next sentence in this paragraph:

How to wash your car without water
Determine if a waterless product is right.
If your car is caked in mud, a waterless car wash will not help and might even scratch the paint of your car. Only use a waterless product if you have minimal dirt or dust.
Otherwise, rinse your car with water to remove dry dirt, then use the waterless product. Use a waterless car wash with wax for an added sheen.
