How is the "best" car wash determined in this list?

WashIndex ranks Magnolia, TX car washes by their Google review rating, restricted to locations with at least 30 customer reviews so that small-sample outliers don't surface. Where ratings tie, the location with more reviews wins. The pool is further restricted to the LLM-classified car wash formats (Express Tunnel, Full Service, Detail Shop, In-Bay Automatic, Self-Serve Bay) so that car dealerships and gas stations with attached washes don't crowd out the actual car-wash operators.

About this ranking

Ranked by Google review rating across LLM-classified car washes in Magnolia, TX. Locations with fewer than 30 reviews are excluded to keep small-sample noise out of the ranking. Ties broken by review count. Dealerships, gas stations, and other auto-related businesses that don't primarily operate a car wash are excluded from the pool at the data-prep stage.
