GHS hazard codes are quoted from the manufacturer’s Safety Data Sheet. PPE tiers below translate those codes and the listed ingredient chemistry; they are not CarCareTruth recommendations.

From the manufacturer’s Safety Data Sheet, Section 8
“H320 (eye irritation Cat 2B) in SDS §2 · wheel-height spray posture creates a face-level exposure path for this classification. Cat 2B does not reach the H319 Cat 2A threshold for recommended.”

U.S. regulatory standard
29 CFR 1910.133(a)(1)
“appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”
ANSI Z87.1 (incorporated via §1910.6)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

TL;DR Clears brake dust from painted alloy, chrome, uncoated aluminum, anodized, and powder-coated wheels in a single 3·5 minute dwell · the deep-red/burgundy color change tells you the iron chemistry is working. SDS pH 6.5·7.0, non-acidic. H315 (skin irritation) and H320 (mild eye irritation) in SDS §2 make eye protection sensible at wheel-height spray posture.
Griot's Heavy-Duty Wheel Cleaner uses a neutral-pH iron-reactive formula to dissolve brake dust on contact. Spray onto a cool, pre-wetted wheel, dwell 3·5 minutes, agitate lightly, and rinse. Owners broadly report single-pass clearance on typical daily-driver contamination, including high-dust vehicles. Formula runs thin · cover the surface fully to avoid dry spots. No brand confirmation on ceramic-coated or PPF wheels; neutral pH is chemistry-compatible but test first.
A solid weekly cleaner for enthusiasts running painted, chrome, or aluminum wheels who want a non-acidic formula safe on their finish. Skip it for tracked-car or multi-season-neglected contamination · a stronger iron remover is the logical step up.
SDS signal word is WARNING with H315 (skin irritation) and H320 (mild eye irritation) only · no corrosive codes, no respiratory hazard codes. No Prop 65 substances in SDS §15 or ingredient list. All wheel cleaners rinse to the drain; aquatic impact status is unknown (SDS §12 no data) · keep wash water off storm drains.
The SDS confirms pH 6.5·7.0 (neutral), which is compatible with ceramic coatings by chemistry. The brand's listing confirms safety on five surface types (painted alloy, chrome, uncoated aluminum, anodized, powder-coated) but does not explicitly name ceramic-coated wheels. Apply conservatively on first use and rinse promptly.
No. The product listing and brand description confirm it is pH-balanced, non-acidic, and non-caustic. SDS Section 9 confirms pH 6.5·7.0. The active ingredient is sodium thioglycolate · an iron-reactive agent that breaks down brake dust by reacting with iron particles, not by acid dissolution.
The brand recommends 3·5 minutes. Spray onto a cool, damp wheel, allow to dwell, agitate gently with a brush if needed, then rinse clean. Pre-wet the wheel with water first per brand instructions.
Yes · the brand explicitly lists uncoated (polished) aluminum as a compatible surface in the product description and listing feature bullets.

How to Clean Your Wheels Without Wrecking the Finish
Wash wheels first, on cool wheels in the shade. Pre-rinse, spray a pH-neutral cleaner, let it dwell, agitate barrels-then-face with dedicated brushes, rinse before anything dries, then dry. Skip acid on clear-coated, polished, or anodized wheels.

Detailing PPE: When You Actually Need Gloves or a Respirator
Most weekend car care needs zero PPE. A small list of chemistries (fluoride wheel acids, isocyanate spray, strong solvent aerosols) genuinely does need gloves, goggles, or a respirator. This guide names the H-codes that trigger each, and points to safer picks by category.
