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 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.

From the manufacturer’s Safety Data Sheet, Section 8
“No H318/H319 in SDS Section 2 mixture classification. SDS Section 11 notes eye contact is 'irritating, and may injure eye tissue if not removed promptly,' and Section 8 specifies safety eyewear against liquid splash, a generic instruction not backed by an eye-specific GHS code at the mixture level. Pump-spray application at close range inside the vehicle cabin places splash/mist contact in a plausible exposure pathway.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H314/H315/H317 in SDS Section 2 mixture classification. SDS Section 11 rates skin-contact hazard as 'low' for typical handling; Section 8 recommends gloves to prevent prolonged contact.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H330/H331/H334 in SDS Section 2 mixture classification (H331 for this product is an ingredient-level Section 3 disclosure only and does not roll up to the mixture). SDS Section 8 still specifies engineering controls, cross-ventilation, and a respiratory-protection program meeting OSHA 1910.134 / ANSI Z88.2 whenever workplace conditions warrant a respirator's use, a conditional (not mixture-classification-driven) instruction. Spray application inside an enclosed vehicle cabin places mist in the breathing zone.”

TL;DR Fluoropolymer-based (PFAS) formula. The SDS carries a DANGER signal word driven by a suspected-cancer classification (H350, Cat 1B), a far more serious hazard profile than the bottle's front-panel "Harmful if Inhaled" warning suggests. Independent, SKU-specific evidence on repellency and durability is thin.
NeverWet Auto Interior is a pump-spray, clear liquid-repelling treatment marketed for upholstery, floor mats, and carpet, sprayed on and left to dry before liquid exposure. SKU-specific bead-test and durability data is thin; detailing forums discuss the broader NeverWet coating technology more than this formula, and describe a coating that can wear through with regular contact. Treat the manufacturer's claims as unverified until more owner data accumulates.
Buyers wanting a low-cost, widely-stocked fabric spray for occasional stain protection may consider it, with modest durability expectations. Buyers who want to avoid PFAS chemistry should look at non-fluorinated alternatives. Anyone aiming to minimize suspected-carcinogen exposure while spraying inside an enclosed cabin should strongly consider a different product.
These are the GHS classifications from the SDS; the PPE tiers below translate that data, not generic Section 8 boilerplate. The mixture is classified DANGER, driven solely by H350 (Carcinogenicity Cat 1B); Section 3's ingredient-level classifications do not roll up into the Section 2 mixture box. Section 15 confirms fluoropolymer (PFAS) via a SARA 313 listing, though the compound's identity is trade-secret. Eyes, skin, and lungs are all situational for the enclosed-cabin spray application, and a Prop 65 warning is corroborated by the SDS's disclosure of ethylene glycol methyl ether. The environment score reflects the PFAS chemistry, which caps the rating regardless of low VOC (11 g/L) and near-neutral pH (7.8).
No. The Safety Data Sheet's Section 15 (SARA 313 reporting table) lists a fluoropolymer as a reportable substance, confirming PFAS chemistry. The specific fluoropolymer compound and its exact concentration are withheld as a trade secret in the SDS, but the fluoropolymer classification itself is not in dispute.
The Safety Data Sheet's Section 2 hazard classification is DANGER, driven by H350 (Carcinogenicity Category 1B, may cause cancer) from one of the disclosed Section 3 ingredients. The bottle's visible front-panel text ('Harmful if Inhaled') reads like a milder warning than the SDS classification actually supports; the SDS is the authoritative hazard document.
Yes. The Amazon listing carries an active Proposition 65 warning, and the Safety Data Sheet's Section 3 independently discloses Ethylene Glycol Methyl Ether at 0.1 to 1.0%, a substance listed under California Prop 65 for developmental and male reproductive toxicity.
Section 8 calls for engineering controls, cross-ventilation by opening doors and windows, and a respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2 whenever workplace conditions warrant a respirator's use. This is a conditional instruction rather than a mixture-level inhalation-toxicity classification, since the Section 2 hazard box for this product does not include an inhalation-toxicity H-code.
