About this analysis
Car wash inventory for Houston, TX is sourced from the WashIndex national car-wash place index,
filtered to places whose Google-Maps-reported city matches Houston, and further restricted to places whose
format the WashIndex LLM classifier identified as a car wash (excluding dealerships, gas stations, and other
auto-related businesses that don't primarily operate a car wash). Inclusion in the parent Houston MSA
dataset is established by point-in-polygon against the official US Census county boundaries (TIGER/Line, 2024).
Operating-quality signals are derived from 61,592 customer reviews
processed through WashIndex's 55-field LLM extraction pipeline. Format classification comes from a separate per-location
website-reading classifier. ZIP-level income data is from the IRS Statistics of Income (tax year 2022) — mean Adjusted Gross
Income per tax return, which is directionally aligned with ACS median household income but available without authentication.
See our full methodology
for the extraction pipeline, validation samples, and aggregation logic. Term definitions in the glossary.
The free WashIndex platform shows every Houston car wash on an interactive map, with the same review-derived
signals and demographic overlays that power this analysis. Filter by format, drive-time, or operator and compare any
location head-to-head with its true competitive set.
