Self-service Car Wash Places

[timzter]

Does anyone know of any self-service car wash places in the DC metroplex (north VA in particular) where you put some money into a machine and you can dispense soap and get several minutes' worth of water from a hose with a *very strong* pressure that you can use to hose down and clean your car with? Looks like this:

I only know of 2 places: One is at the gas station at the southeast corner of I-395 and Glebe Rd, but its water pressure is not strong enough; and the other is near a strip mall in Warrenton (can't remember exactly where) but that's too far!

If you know of a website that shows such car wash places, please share.

I find that touchless drive-thru car wash places don't clean your car very well.

Does your Lexus have a POI "Carwash" category or do you have a portable GPS that has one? Our Garmin Nuvi shows every automatic and manual carwash in our area so I'm guessing you could do the same thing where you live.

I can point you to some up in Gaithersburg...
