Step 01 // The attestation body
WashAttest is the attestation standard for commercial and fleet wash vendors. It defines what a compliance file, an operational scorecard, proof of work, and a dispute record have to contain before a listing can be called attested. A star rating is not an attestation.
The attestation record
A star rating says someone was happy. It does not say the vendor can discharge wash water at a facility, that insurance is current, or that last quarter's service window was hit. Those four records are the attestation. They are defined in the WashAttest Standard.
A review counts toward an attestation only when it names an operator role — facility, fleet, or property manager — and how many jobs that reviewer has bought. Anonymous ratings do not.
General liability, workers’ compensation, business license, and stormwater or NPDES status. Each item carries an expiry date and the date it was last checked.
On-time rate, rework rate, response time, units per night, retention, and incident rate over a trailing twelve months. The window and the sample size are part of the record.
Before-and-after documentation, wash logs, per-unit service reports, and stormwater discharge logs, tied to a visit and reconcilable to billing.
The same four records, compared on one page, then exported as a request-for-quote packet for the buyer’s own process.
A challenge stays on the record with the claim, the response, the evidence, and the outcome: upheld, amended, removed, or still unresolved.
Sourced ratings
Checked Oct 28, 2026
These are star averages as published on each business's public Google profile, read on Oct 28, 2026. A sourced rating is quoted, not issued. It is not a WashAttest attestation, and it is not a substitute for the compliance file, scorecard, and proof of work defined in the standard. Ratings move, so the check date is part of the record.
