From the manufacturer’s Safety Data Sheet, Section 8
“H317 (skin sensitizer, Cat 1) confirmed in SDS §2. No H312 or H314 present, so the required tier does not apply, but sensitization risk means gloves are recommended by the classification regardless of contact duration.”

“appropriate hand protection when employees' hands are exposed to hazards such as those from skin absorption of harmful substances.”

“No H332, H335, H330, or H331 at the mixture level. SDS §7/§8 direct general ventilation of the work area in generic language rather than a named inhalation scenario, so lungs protection is situational in an enclosed garage rather than not needed.”

TL;DR Iron Buster turns a fast purple within a couple minutes on contaminated wheels and paint, and reviewers rate its cleaning power well, though a few say heavy contamination needs more product than competitors. The DANGER signal word means eye protection is required and gloves are recommended, and the manufacturer's SDS discloses a California Prop 65 warning the Amazon listing does not show.
Spray onto washed wheels or paint and watch it turn purple as the reaction pulls bonded iron out, then rinse after a 2 to 5 minute dwell without letting it dry first. Reviewers describe the color-change as vivid and quick on typical brake dust, though a few recent reviews say heavier buildup needed a second pass. Amazon's spec sheet calls it "unscented," but the manufacturer SDS lists the odor as cherry, and reviewer opinions on smell split between "barely noticeable" and "strong and lingering." Work in a ventilated area either way.
A solid pick for owners doing routine iron decon on wheels and paint who want a visible color-change indicator and are comfortable with a DANGER-rated chemical, gloves, and eye protection. The pH-balanced formula and lack of surface-damage reports make it workable ahead of a wash or coating maintenance. Skip it if you shop by fragrance-free labeling: the "unscented" Amazon claim does not match the manufacturer's cherry-scent disclosure.
The SDS classifies this at DANGER, driven by H318 (serious eye damage), plus H302 (harmful if swallowed) and H317 (skin sensitizer). Eye protection is required and gloves are recommended. The same SDS discloses a Prop 65 warning for ethylene oxide, a trace surfactant residue, that the Amazon listing omits. Rinse water carries the full volume to the drain: two of the three surfactants have documented aquatic toxicity, and the mixture is classified as not rapidly biodegradable.
Yes. The manufacturer safety data sheet discloses a Prop 65 warning for ethylene oxide, a trace processing residue from one of the surfactant ingredients. The Amazon listing for this product does not display a Prop 65 warning, but the SDS disclosure is the more current and complete safety document, and independent retailer listings for this product confirm the same warning.
No, despite what the Amazon listing's spec table claims. The manufacturer safety data sheet lists the product's odor as cherry-scented at Section 9. Buyer reviews on other retail sites are split on odor intensity, with some describing it as noticeably strong and lingering and others calling it mild for the category.
The SDS classifies the product at DANGER signal word with H318 (serious eye damage), which makes chemical eye protection required. It also carries H317 (skin sensitizer), which means gloves are recommended regardless of how long you expect to be in contact with the product. The SDS does not carry an inhalation-harm code at the mixture level, but general ventilation is still directed during the dwell period.
The manufacturer markets it as safe for painted surfaces, chrome, aluminum, and alloy wheels, and the SDS confirms a mildly acidic pH of 5.5, above the range where etching risk becomes a significant concern for most coatings. No coating or wheel-finish damage complaints turned up in the retailer reviews checked for this write-up. The manufacturer still directs a spot test on wheel finishes before full application, which is worth doing given the limited independent testing data available for this specific product.
The manufacturer directs a 2 to 5 minute dwell time, and warns against letting the product dry on the surface before rinsing with water or a pressure washer. On a hot day or in direct sun, work smaller sections so the product does not dry out mid-dwell.
