Listed for drivers in and around San Marcos, CA, these 24 shops wash cars. What each one says about wash types, monthly plans and hours comes from its own website; ratings and quotes come from public reviews.
19 of the 24 shops list weekend hours. Check those hours against the wash type you want, since a tunnel, a self-serve bay and a hand wash do not always keep the same schedule.
