About these prices

The cheapest unlimited monthly plan we found in San Marcos is at Quick N Clean Car Wash on 1644 Aquarena Springs Dr, at $19.95 a month. The cheapest single wash is at Suds Deluxe Car Wash, from $12. A typical unlimited plan costs about the same as 2 single washes, so it pays off if you wash more often than that each month.

Prices are the cheapest regular ones each car wash lists on its own website, last checked in November 2026. Intro deals and add-ons are left out, and prices can differ by location. Each listing has a link to tell us when a price changes. All car washes in San Marcos.
