How to Use the Free Car Wash at Gas Stations?

[DeBrynlee]

First, refuel your car at the gas station. Typically, free car wash services are offered only when the refueling cost reaches a certain threshold. After completing the payment for refueling, if you meet the conditions for a free car wash, the service staff will provide you with a free car wash card. When it's your turn for the car wash, drive your car to the entrance of the automatic car wash machine and hand the car wash card to the staff. Then, listen to the staff's instructions on how to operate the machine. Drive your car onto the car wash machine, shift into neutral, release the handbrake, do not turn off the engine, close the automatic wipers and windows, and fold in the rearview mirrors if possible.
