Sonax Beast Wheel Cleaner (1 Liter)

Sonax and multiple retailers list ceramic-coated and polished finishes among the surfaces Beast is safe on, alongside chrome, aluminum, steel, clear-coated, painted, and PVD wheels, at the SDS-confirmed pH of 5.15. That claim is not yet backed by independent community testing since this is a newer release (SDS issued February 2025). The brand's own instructions caution against use on anodized wheels and brake systems without testing an inconspicuous spot first.

Both use the same iron-reactive active family, but Beast's SDS discloses a materially higher concentration of sodium thioglycolate (10-30%) than Full Effect's 5-10%, and adds a phosphonate chelant that Full Effect's SDS does not list. Beast also carries a Warning signal word and a single, internally consistent Skin Sensitization Category 1B classification, while Full Effect's SDS carries no signal word and an internally contradictory sensitization classification. The two ship under separate SONAX article numbers with separate SDS filings. Neither is the objectively better choice: Beast is the stronger, higher-concentration formula, while Full Effect has the longer independent track record.

The SDS's Section 8 specifies gloves resistant to chemical penetration, driven by the Skin Sensitization Category 1B classification (H317) that is the SDS's sole GHS hazard classification; the SDS itself does not assign a GHS eye-hazard code. The physical retail bottle carries its own separate front-panel caution: 'Harmful if swallowed. Eye irritant.' That is a US consumer FHSA/CPSC label caution, a different regulatory framework than the SDS's OSHA HazCom/GHS classification, and the two can legitimately diverge. The printed label warning is a real, standing caution regardless of the SDS's silence on a specific eye-hazard code, which is why eye protection sits at recommended rather than the milder tier the SDS reading alone would suggest. Respiratory-protection language in the SDS is boilerplate tied to exposure-guideline thresholds rather than a specific inhalation hazard code, relevant mainly if used in an enclosed garage with the door closed.

No. The SDS's Section 15 states explicitly that the product does not contain any substances known to the State of California to cause cancer or reproductive harm, and a chemistry cross-check of all three disclosed ingredients (sodium thioglycolate, the cocamidopropyl-betaine-family surfactant, and the PBTC chelant) against the state's Proposition 65 list found no matches. That is an affirmative clearance rather than an absence of data.

The active reacts with bonded iron particles to produce a deep red to burgundy color, the expected reaction for this chemistry family, not the purple sometimes used in marketing copy, which is characteristic of a different type of iron-reactive chemistry. Sonax's guidance calls for a two-to-five-minute dwell before rinsing with a strong jet; letting the product dry on the wheel is the main cause of streaking, so timing the rinse matters more than exact dwell length.
