Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 germ-cell mutagenicity — classified as suspected of causing heritable genetic damage.
GHS Category 1 carcinogenicity — classified as suspected of causing cancer with repeated or prolonged exposure.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.
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
“No eye H-codes (H318/H319) in SDS §2 mixture classification. Aerosol form factor creates mist at face height during terminal application · eye protection is relevant during the spray step.”

From the manufacturer’s Safety Data Sheet, Section 8
“No skin H-codes (H314/H315/H317) in SDS §2 mixture classification. Direct hand contact with dissolved corrosion slurry during the wipe-down step is the realistic exposure path; the slurry contains lead sulfate and lead oxide from the battery terminals.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H335 in SDS §2, but SDS §8 explicitly specifies a NIOSH-approved organic vapor respirator when ventilation is inadequate, and the propellant fraction carries H340 (germ-cell mutagenicity) and H350 (carcinogenicity) classifications. Per health.md §Lungs escalation path: aerosol + explicit SDS §8 respirator + H340/H350 ingredients escalates from situational to recommended. Use outdoors or in a well-ventilated space; avoid enclosed garages with the door closed.”

“Each employer shall assure that no employee is exposed to an inhalation concentration of any substance shown in Tables Z-1, Z-2, or Z-3 in excess of the limits in the tables.”

TL;DR Handles routine terminal corrosion in a three-minute spray-and-rinse · the ammonia-alkaline formula dissolves lead sulfate buildup without a wire brush on light-to-moderate cases. No color-change indicator. The petroleum-distillate propellant carries germ-cell mutagenicity and carcinogenicity classifications (H340/H350) · the DANGER signal word is health-driven, not from flammability. Use outdoors or in a well-ventilated space.
Permatex 80369 sprays on, reacts with corrosion for about three minutes, and rinses clean. The ammonia chemistry neutralizes acid residue · not just a surfactant wash · though unlike baking-soda formulas, there is no visible fizzing or color change. A straw attachment gives adequate directional control; some overspray to the housing is expected. Owners broadly report consistent performance on routine maintenance buildup.
Right for routine terminal maintenance · light-to-moderate white-blue buildup on a battery in regular service. Skip it for thick, crusty buildup from years of neglect; that severity typically needs a wire brush. This is not the mild baking-soda formula many buyers expect · the propellant carries DANGER-level health classifications, making bicarbonate-based alternatives worth considering for buyers who want to minimize exposure.
DANGER is health-driven: H340 (germ-cell mutagenicity Cat 1B) and H350 (carcinogenicity Cat 1A) from the petroleum-distillate propellant fraction. California Prop 65 confirmed per SDS §15. SDS §8 specifies an organic vapor respirator when ventilation is inadequate. Extremely flammable · keep away from ignition sources. No eye or skin GHS hazard codes in SDS §2. Environment 7.0: no aquatic H-codes, no PFAS, co-solvent VOC below 20 g/L. The corrosion dissolved from battery terminals contains lead sulfate · wash hands after handling the slurry, and avoid rinsing waste into storm drains.
The Safety Data Sheet for Permatex 80369 Battery Cleaner Aerosol (5.75 oz) carries a DANGER signal word, with classified hazards including H222 (extremely flammable aerosol); H225 (highly flammable liquid and vapour); H280 (contains gas under pressure; may explode if heated). The Amazon listing also carries a California Prop 65 warning. See the PPE breakdown above for use-case-specific guidance translated from the SDS hazard codes.
CarCareTruth scores Permatex 80369 Battery Cleaner Aerosol (5.75 oz) at 6.1 out of 10 on the composite CCT score, with a health sub-score of 4.3/10. The CCT score blends real-world effectiveness, ingredient health impact pulled from the manufacturer's safety sheet, and environmental footprint against a published category rubric.
