The 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 2 acute oral toxicity — classified as toxic if swallowed.
GHS Category 2 acute dermal toxicity — classified as toxic in contact with skin.
GHS Category 2 acute inhalation toxicity — classified as toxic if inhaled.
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.

TL;DR Methanol-based aerosol deicer; health score 1.2/10 is correct for methanol chemistry, not an error. The DANGER label is health-driven: SDS §2 classifies this product as acutely toxic by inhalation, skin contact, and ingestion, with organ damage to the CNS and optic nerve. Wear goggles, nitrile gloves, and a respirator per SDS §8. Label claims −25°F; cold-climate community verification is limited.
Penray 5216 is a methanol-based aerosol deicer that clears ice from windshields and thaws frozen door locks. The formula cannot freeze at any realistic outdoor temperature, supporting the −25°F label claim; cold-climate community evidence is limited so deicing speed and low-temp scores are capped conservatively. Surface safety is solid: no salt or chloride content, and owners report no paint, seal, or trim damage. The 11 oz can is below the category standard of 16·22 oz.
Right for situations where a very-low freeze-point formula is needed and appropriate PPE is available. Not a casual glove-box spray: the SDS requires goggles, gloves, and a respirator. Buyers wanting a lower-hazard aerosol deicer should choose an IPA-based formula; those products score 7·9 on health with only situational eye protection.
SDS §2 carries a health-driven DANGER signal word from H301, H311, H331, and H370 (organ damage to CNS and optic nerve). Prop 65 applies per SDS §15. The H311 dermal absorption route and H370 optic nerve pathway are why all three PPE categories translate to required: wear goggles, nitrile gloves, and an organic-vapor respirator. Environment 6/10: VOC above 550 g/L (−2.0) offset by SDS §12.3 confirmed biodegradability (+1.0).
The Safety Data Sheet for Penray 5216 Windshield Spray De-Icer carries a DANGER signal word, with classified hazards including H222 (extremely flammable aerosol); H280 (contains gas under pressure; may explode if heated); H301 (toxic if swallowed). 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 Penray 5216 Windshield Spray De-Icer at 5.6 out of 10 on the composite CCT score, with a health sub-score of 1.2/10. 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. See the methodology link on this page for the full scoring breakdown.
Per the Safety Data Sheet ingredient disclosure: Methanol (CAS 67-56-1): 60·100%; Carbon dioxide (CAS 124-38-9): 5·10%; 2-Butoxyethanol (CAS 111-76-2): 1·5%; Morpholine (CAS 110-91-8): 0.1·1%; 2-Methoxyethanol (CAS 109-86-4): <0.1%. Source: SDS v1.0, 2014-06-11, Fastenal CDN.
