Mastic Beach Self Service Car Wash is a convenient and 24-hour location for a light, quick car wash. It is cost-effective, recently added safer tap-to-pay, and provides a workout. The actual place is ok, but it is becoming run down and not cared for. The setup and brush power washer combo lack sufficient water pressure, especially for heavy grime, and supplies in the vending machine are often unavailable. It is not the greatest, but it is very convenient for a basic clean.
Great place when it isn't being used as a personal dump.

Well worth the money, was able to get all the salt & snow of my vehicle

Very convenient and I've never had a problem here. It's a workout too because the faster you wash your car, the cheaper it is. Recently added tap-to-pay, which is much safer from skimming. Still my preferred method to wash the car.
