} About this profile
Every operating-quality signal on this page is derived from 77 customer reviews of Tidal Wave Car Wash locations, processed through WashIndex’s 55-field LLM extraction pipeline. Competitor counts within 1 / 3 / 5 mi rings are computed by haversine distance against the WashIndex location index across the chain’s states and immediately adjacent ones (sister sites in the same chain are excluded). Monthly review and rating trends are pulled from the raw Google Maps review feed. 1 spam-flagged reviews were excluded from the aggregates.
