CarCareTruth's Analysis
Last reviewed May 15, 2026
TL;DR DANGER-rated aerosol with a Prop 65 warning — the carrier contains a California-listed carcinogen, and one ingredient carries a reproductive toxicant classification. Community-confirmed penetration on light-to-moderate rust in 5–15 minutes. Aerosol mist in enclosed spaces is the primary inhalation concern.
What it is and how it performs
PB Blaster wicks a thin solvent into corroded threads to free seized fasteners. Community-confirmed dwell time on light-to-moderate rust is 5–15 minutes; heavy rust may need a second coat. The aerosol straw reaches blind bores and undercar hardware. Community data confirms a light oil film prevents re-seizing for a few weeks — useful for staged work, not a long-term corrosion inhibitor.
Who should buy this — and who should skip it
Strong choice for a homeowner with a single stubborn bolt or occasional teardown work. Skip it for frequent enclosed-space use — DANGER signal word, confirmed Prop 65 carcinogen, and reproductive toxicant classification at the mixture level are documented SDS hazards that compound with repeated aerosol exposure.
Safety and environmental impact
DANGER driven by an aspiration hazard if swallowed and a reproductive toxicant classification. Prop 65: aromatic solvent fraction contains naphthalene (California-listed carcinogen). Eye irritation classified at mixture level; aerosol mist is the exposure pathway. Do not induce vomiting if swallowed — seek medical attention. No H335 at mixture level; aerosol mist in an enclosed space is the inhalation risk.
Environmental: petroleum-distillate carrier, not biodegradable, two aquatically toxic ingredients, VOC above 550 g/L.
