+
WashIndex ranks San Luis Obispo, CA 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.
