Self-Service Car Washes in Maryland

50 of the 356 car washes we track in Maryland have self-serve wash bays. Coin-op bays with a pressure wand are a different business from an express tunnel — and the one thing a map search cannot separate. Every listing here has its bays confirmed from the wash's own website or data. Full listings for every city are on the Maryland page.

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.
