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

+
WashIndex ranks Vallejo, 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 restricted to the LLM-classified car-wash formats that actually wash vehicles on site — Express Tunnel, Full Service, In-Bay Automatic, Self-Serve Bay and Hand Wash — so that detailing/tint shops, car dealerships and gas stations with attached washes don't crowd out the actual car-wash operators.

About this ranking

LLM-classified car washes only — dealerships, gas stations, and other adjacent businesses are excluded at the data-prep stage. 30-review minimum keeps small-sample outliers out. The dominant #1 here is stable to ordinary rating drift.
