Mercer Island Auto Spa is the only full-service car cleaning facility on Mercer Island, offering both automatic exterior washing and self-serve car washing options. The management takes pride in providing an environmentally sound alternative to driveway and parking lot car washing, preventing oils, road grime, and soap from entering the storm sewer system and keeping Lake Washington and Puget Sound cleaner. The Auto Spa has been providing quality services since 1995. The Automatic Car Wash and Auto Detailing are open daily from 8 am to 6 pm, while the Self-Serve Car Wash and Vacuums are available 24 hours. Customers have praised the well-kept and neat facility, indicating that the owners care about the place. The self-serve car wash is a popular choice, with powerful "gun" hoses that can make users feel like they're about to fly away. Vintage vacuums and air fresheners add to the character of the Auto Spa, though some customers find the vacuums a bit outdated. Overall, the Mercer Island Auto Spa offers a convenient and satisfactory car washing experience, with friendly and efficient attendants. Customers recommend bringing their own towels for drying and detailing, as well as quarters for the vacuums, which could use an improved system.
One of the best small businesses on the island. Always professional, attentive and friendly with great pricing 💯

Used self service bay. Takes card as payment in the bay, which is great. Bit pricier than other self service places. Not enough space to park and wipe down. Couldn't find office/personnel. Did not use automated wash, so can't comment. Wish there was a 3.5 star option.

I love how conveniently located this is near the freeway. We have no self service car wash in Central Seattle anymore so we pop over here when coming home from the mountains on I-90.
