Car washes are a great way to keep your car looking good and running smooth. However, many car owners don’t know how much should be tipped for car wash services. Generally, car wash tipping etiquette suggests that you tip at least 10-20%. This amount may differ based on the level of service provided or what you can afford. If you are happy with the car wash job, showing appreciation with a generous tip of 20-50% is appropriate; if not, reducing the amount is understandable. Be sure to consider various factors when deciding the tip amount such as quality of service and overall cost. Ultimately, car wash tipping is a matter of personal preference and should be based on you budget and satisfaction with the car wash service.
