From the manufacturer’s Safety Data Sheet, Section 8
“H318 (serious eye damage Cat 1) in SDS §2 · GHS05 corrosive pictogram present for the eye-damage classification. Serious and potentially irreversible eye damage is the confirmed hazard classification. Upward spray application into wheel arches increases mist-to-face pathway. Safety goggles or splash glasses required by H318 classification.”

U.S. regulatory standard
29 CFR 1910.133(a)(1); 1910.151(c)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals, acids or caustic liquids…”
ANSI Z87.1 (chemical splash protection — incorporated via §1910.6)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

From the manufacturer’s Safety Data Sheet, Section 8
“H315 (skin irritation Cat 2) is present in SDS §2. The SDS does not classify skin harm (H312) or skin corrosion (H314) at product level · SDS §11 confirms no skin harm code. GHS05 appears because of H318 (eye damage) · it carries no implication for skin. H315 without H312 or H314 places skin PPE at situational: nitrile gloves warranted when handling during prolonged or repeated contact.”

From the manufacturer’s Safety Data Sheet, Section 8
“No inhalation H-codes at product level · SDS §11 confirms not classified as hazardous through inhalation (H332, H335, H331 are absent at product level). SDS §8 notes respiratory protection 'necessary if a mist forms or occupational exposure limits are exceeded.' The sulfur odor during dwell is a sensory indicator of thioglycolate volatiles. Apply outdoors or with adequate airflow.”

TL;DR DeCon Pro turns a vivid purple on brake-dusted paint and wheels and dissolves iron in a single application at the labeled dwell time · community evidence confirms both the color-change reaction and the removal performance. **DANGER signal word** on the SDS (H318 serious eye damage, H315 skin irritation) · safety glasses are required by the H318 classification; gloves are warranted for prolonged contact with the thioglycolate active. Confirmed pH 7.28 (neutral) from SDS; coating-safe by community consensus.
Spray onto cool paint panels, wheels, or glass, watch the product shift from clear to deep purple as the thioglycolate active pulls iron oxide out of the surface · the more contaminated the panel, the more vivid the reaction. Dwell 3·5 minutes (longer for heavy contamination), then pressure-rinse. A strong community evidence base across r/AutoDetailing and Detailing World confirms single-application removal on standard brake-dust and moderate rail dust loads on both paint and wheels. The dual-purpose positioning is supported by the chemistry · monoethanolamine thioglycolate reacts with iron regardless of substrate. The sulfur odor during dwell is present and notable by community consensus; use outdoors. Quality score 7.3/10 · solid mid-tier performance without the enthusiast-tier coating-ecosystem documentation of competitors like CarPro IronX.
The right pick for detailers who want a single product covering both paint iron decontamination and brake-dust wheel cleaning at a competitive price, especially those already in the Chemical Guys ecosystem. It's a reliable choice before polishing, claying, or laying a maintenance coat on ceramic-coated paint or PPF. Skip it if odor control is a priority · Adam's Iron Remover's orange-scented reformulation is the strongest scent-mask in the pH-neutral category. Skip it if you're maintaining a specialized ceramic coating system that specifies a brand-approved iron remover; CarPro IronX has the deeper ecosystem documentation there.
The SDS (SPI215, rev. 2024-12-05) carries a DANGER signal word, driven by H318 (serious eye damage Cat 1) from the pH co-buffer thioglycolate active at 10·25%. The GHS05 corrosive pictogram on the label reflects this eye-damage classification · it is the eye hazard code, not a skin-corrosion indicator. Safety glasses or goggles are required by H318 when handling. H315 (skin irritation Cat 2) is the skin code; the SDS does not carry H312 (skin harm) at product level · nitrile gloves are warranted for prolonged or repeated contact based on H315. The SDS §11 explicitly confirms the product is not classified as hazardous through inhalation (no H332, H335, or H331 at product level) · the sulfur odor during dwell is a comfort consideration and a ventilation signal, not an inhalation hazard classification. Flash point 69°C (157°F) · combustible liquid Cat 4, non-flammable under normal ambient use conditions. On environment: the formula contains 4-nonylphenol ethoxylate, a surfactant that degrades to 4-nonylphenol, a known endocrine disruptor; environment score 5/10 reflects the drain-destined rinse pathway, confirmed non-biodegradable NPE surfactant, and ingredient-level aquatic toxicity. Rinse to a sanitary drain, not a storm drain.
The SDS discloses a pH of 7.28, which is within the neutral range typically safe for ceramic coatings and PPF. Community evidence on r/AutoDetailing and Detailing World broadly supports the coating-safe claim for standard dwell times (3·5 minutes). For polished aluminum or anodized wheels, spot-test a hidden area first.
The purple color is iron-thioglycolate · the reaction product of the monoethanolamine thioglycolate active with iron oxide on the surface. The reaction is selective for ferrous iron, so the purple intensity reflects actual iron contamination level. Areas that don't turn purple have little to no bonded iron.
The SDS (SPI215, rev. 2024-12-05, §15) explicitly states California Proposition 65 is Not Applicable for this product · neither cancer nor reproductive harm listings apply. Amazon's platform sometimes displays a Prop 65 label on DeCon Pro listings, but this is a known false positive not supported by the SDS or ingredient cross-check.
The chemistry works on both · monoethanolamine thioglycolate reacts with iron oxide regardless of substrate. Community evidence confirms effective iron removal on painted surfaces, glass, and aluminum wheels in a single product. For vehicles with very heavy industrial fallout or rail dust on paint, a dedicated iron remover with higher active concentration may be needed.
Both use pH-neutral thioglycolate chemistry with similar active ingredient classes. CarPro IronX has deeper documentation within CarPro's coating maintenance ecosystem; DeCon Pro is positioned more broadly as a combined iron remover and wheel cleaner. Independent side-by-side community tests show comparable performance on brake dust, with some owners noting CarPro slightly ahead on heavy paint contamination and DeCon Pro competitive on wheel cleaning efficiency.
The SDS classifies H315 (skin irritation Cat 2) at the product level. Nitrile gloves are warranted for prolonged or repeated contact · the H315 classification is the basis for that, not generic SDS boilerplate. Brief incidental contact during normal spray-and-rinse use is a lower-concern scenario, but gloves are the practical choice when handling the product repeatedly or applying it to multiple panels.

Guide
Detailing Chemicals That Damage Paint, Trim, or Your Lungs
Most paint, trim, and respiratory damage from car-care products traces to a short list of chemistries (fluoride wheel acids, strong solvents, high-pH degreasers, isocyanate sprays, methylene chloride). This guide names the H-codes, the failure modes, and the catalog pages that show which products carry them.

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.
