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 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 on skin:
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.

Translated from the manufacturer’s Safety Data Sheet, Section 2
H370 STOT SE Cat 1 targets the CNS and optic nerve as a systemic toxicity route; SDS §8 specifies eye protection. GHS08 health-hazard pictogram is present. Required given H370 targets eyes directly.
U.S. regulatory standard
29 CFR 1910.133(a)(1)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”

H311 classifies this product as acutely toxic by dermal contact (Cat 3); methanol absorbs through skin causing systemic poisoning. SDS §8 specifies protective gloves. Required given the H311 dermal toxicity classification.
U.S. regulatory standard
29 CFR 1910.132(d); 1910.138(a)
“appropriate hand protection when employees' hands are exposed to hazards such as those from skin absorption of harmful substances.”

PPE tiers translate the manufacturer’s SDS and U.S. regulatory standards. Not professional safety advice. How we report safety.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR Methanol-based aerosol deicer; health score 1.2/10 reflects genuine acute toxicity, not an error. SDS Section 2 finds it toxic if swallowed, inhaled, or skin-absorbed, with CNS and eye organ damage, so goggles, gloves, and a respirator are required. Label claims -25°F; cold-climate verification is limited.
Community cold-climate verification is limited: reviews confirm reliable ice clearing, but few buyers report sub-zero test conditions, so the label's -25°F claim (chemically plausible since methanol does not freeze until -144°F) is not independently confirmed at that extreme. This is a methanol-based aerosol formula rather than the more common isopropyl-alcohol deicer, and methanol carries real acute-toxicity hazards IPA formulas do not. Surface safety is solid: no chloride content, and owners report no paint, seal, or trim damage. The 11 oz can is smaller than the 16-22 oz category standard and also thaws frozen locks.
Right for buyers who need a very-low freeze-point formula and will use the required PPE every time: goggles, gloves, and a respirator. Not a casual glove-box spray. Buyers wanting a lower-hazard aerosol deicer should choose an IPA-based formula instead.
SDS Section 2 assigns DANGER from real health hazards: toxic if swallowed (H301), skin contact (H311), inhalation (H331), and organ damage to the CNS and optic nerve (H370). Section 15 confirms Prop 65 for methanol and 2-methoxyethanol. H311 and H370 push all three PPE categories to required. Environment scores 6/10: high VOC is offset by SDS Section 12.3's confirmed biodegradability.
Yes. This is a methanol-based aerosol formula, not a salt- or chloride-based deicer, so it carries no corrosion risk for paint or metal. The manufacturer states it is safe for painted finishes and harmless to painted rubber components, and owners have not reported paint, trim, or seal damage. Independent multi-season forum confirmation is still limited.
Most consumer deicers use isopropyl alcohol and score in the 7 to 9 range on health. Penray 5216 is methanol-based instead, and SDS Section 2 classifies methanol as acutely toxic if swallowed, inhaled, or absorbed through skin, with organ damage to the CNS and optic nerve. That genuine acute-toxicity profile, not a chemistry error, drives the 1.2/10 score.
SDS Section 8 specifies eye protection, protective gloves, and respiratory protection in confined or poorly ventilated spaces. Because methanol absorbs through skin and its vapor is toxic if inhaled, all three PPE categories translate to required: safety goggles, nitrile gloves, and an organic-vapor respirator, not the situational protection typical of IPA-based deicers.
The chemistry supports it: methanol does not freeze until about -144°F, so the formula cannot lock up at any realistic outdoor temperature. However, no independent cold-climate community reports specifying sub-zero test conditions were found among owner reviews, so the -25°F label claim is chemically plausible but not independently confirmed at that extreme.
Yes. The product is positioned for both windshield de-icing and frozen door lock applications. Spraying into a lock cylinder briefly concentrates methanol vapor in a small enclosed gap, which is part of why the lungs PPE tier stays elevated; a single brief application is the intended use case, not sustained multi-lock sessions without ventilation.
