Bring quarters anyway. Most self-serve bays now take cards or an app, but in small towns the changer is still the heart of the operation — and the wand timer does not pause while you dig for a card.

Good to know

What is a self-service car wash?

Open bays where you park and wash the car yourself with a pressure wand and foam brush, paying for time — typically a few dollars for several minutes. It is the cheapest way to wash a truck bed, floor mats, or anything an automatic tunnel will not take.

How much does a self-service bay cost?

Usually $2-5 to start, buying 3-5 minutes, then quarters or card swipes to add time. A thorough wash typically runs $6-10 — still well under an express tunnel with the same result if you put in the elbow grease.
