From the manufacturer’s Safety Data Sheet, Section 8
“H318 (serious eye damage Cat 1) from SDS §2 · GHS05 corrosive pictogram. At wheel height with pump-spray or foam-gun application, face-level mist is a direct eye exposure pathway. The SDS chemistry classifies this as serious eye damage Cat 1.”

TL;DR Clears heavy brake dust and road grime from chrome, aluminum, painted, and powder-coated wheels in a single pass. DANGER signal word · H314 (skin corrosion Cat 1) and H318 (serious eye damage Cat 1) from the SDS chemistry mean goggles and chemical-resistant gloves are required at wheel height.
Spray or foam onto rinsed wheels, dwell 1·2 minutes, agitate with a brush if needed, and rinse. The concentrate foams from a pump-up sprayer or foam gun and clings to vertical surfaces while dissolving brake dust and grime. Professional and community evidence ranks it among the most capable non-acid cleaners for heavy contamination on painted alloy, chrome, powder-coated, and steel wheels. No iron-reactive color change · any color shift during use is lifted brake dust in the foam, not a chemical reaction indicator.
Right for detailers with heavy brake dust on painted, chrome, or powder-coated wheels · the gallon is the economy choice for multi-vehicle or mobile work. Skip it if you want iron-reactive color confirmation, or if your wheels are polished bare aluminum or anodized, where the alkaline pH poses corrosion risk.
H314 (skin corrosion Cat 1), H318 (serious eye damage Cat 1), H317 (skin sensitization Cat 1) · DANGER signal word. Chemical-resistant gloves and goggles required at wheel-height spray posture per the SDS hazard codes. No respiratory H-code; ventilate in enclosed spaces. SDS §15 confirms no Prop 65 listing. Drain-destined; aquatic toxicity confirmed per SDS §12; no PFAS.
Yes · the brand explicitly claims safe use on chrome in the product listing. Unlike strongly alkaline formulas that warn against chrome, P&S Brake Buster's community record on chrome is consistently positive with no widespread damage reports. Keep dwell time to 1·2 minutes and rinse promptly.
No. P&S Brake Buster is an alkaline surfactant-plus-builder formula · it does not contain iron-reactive chemistry. The liquid is purple (SDS §9 color: purple) before application. Any color change during use reflects lifted brake dust suspended in the foam, not an iron dissolution reaction.
The brand sells it ready-to-use at full strength for heavily contaminated wheels. For maintenance washing on lightly contaminated wheels, professional detailers commonly dilute it 1:4 to 1:10 in a pump-up sprayer or foam gun · though P&S does not publish official dilution ratios for this gallon version.
The SDS lists DANGER as the signal word, driven by H314 (skin corrosion) and H318 (serious eye damage) from the strongly alkaline pH 12.5 formula. For a home detailer this means chemical-resistant gloves and eye protection are required any time you spray at wheels. For outdoor use with brief dwell times, no respiratory protection is required.
Yes · the same Brake Buster concentrate chemistry, just in a different size format. The gallon (B07RTZBGWX) is the professional economy size; the pint (B0779KHK24) is the entry-level size. Both carry the Double Black by Renny Doyle branding and the same SDS (N26 product code family).
