Wash and rinse your car thoroughly and you can leave the water on the car after washing.
Use the Pika Pika Rain Microfiber Cloth that comes with the Nano Pika Pika Rain.
Get the microfiber cloth wet and wring it out. Spray Nano Pika Pika Rain 1 to 2 times onto the microfiber cloth.
Using the microfiber cloth, wipe away water left on the car body until the area you want to work on becomes dry.
*Please work only on a small area at a time (1m x 1m, such as a door, or half of the hood).
