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 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
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.

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8.2.2 lists Indirect Vented Goggles as the specified eye/face protection. SDS §11 states: 'Sprayed material may cause eye irritation.' No H319 eye irritation classification appears at the mixture level in SDS §2. Aerosol spray inside the vehicle cabin at face level creates a plausible eye contact pathway.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 (version 5.04, 2026-05-06) classifies H336 (STOT SE Cat 3 · may cause drowsiness or dizziness) and H370 (STOT SE Cat 1 · causes damage to organs, cardiovascular system). H336 is an inhalation pathway code applicable under the aerosol use scenario. H370 appears with a physician note in SDS §4: 'Exposure may increase myocardial irritability. Do not administer sympathomimetic drugs unless absolutely necessary.' SDS §7 contains a non-boilerplate enclosed-space restriction and specifies: 'Use only outdoors or in a well-ventilated area.'”

TL;DR Reliable aerosol fabric protection · the bead test holds on car fabric seats and carpet for 4·6 weeks on a daily driver, consistent with quarterly reapplication rather than the biannual claim on the label. Non-PFAS formula: the current formulation (SDS version 5.04, May 2026) contains no fluoropolymer or fluorotelomer ingredients. DANGER signal word: the SDS classifies organ damage (cardiovascular system) and aspiration hazard · apply with all vehicle doors fully open. California Prop 65 warning present.
Scotchgard Auto Fabric & Carpet Water Shield sprays a silicone-based protective barrier onto fabric seats, carpet, and floor mats in seconds · the aerosol format makes even coverage easy and the coating dries within 1·2 hours. The bead test is the central performance story: owners consistently document liquid beading and rolling off treated fabric on direct pours, with the protection window holding through normal vacuuming and light passenger contact for 4·6 weeks. Reapplication is the trade-off · the label says every cleaning or every six months, but the community consensus clusters around quarterly reapplication in normal daily-driver conditions. Stain resistance is strongest for common liquid spills (coffee, soda) when blotted promptly; muddy and particulate soiling requires faster action on treated fabric. Carpet protection holds slightly longer than seat fabric, where passenger contact is more abrasive.
A practical choice for daily drivers with standard woven fabric seats and OEM carpet who want quick, broadly available protection from spills and wet weather. The aerosol format is the right tool for car carpet and floor mats · complete, even coverage without soaking or over-application. Buyers who want to avoid PFAS chemistry will find the current silicone-based formula confirmed PFAS-free in SDS §3. Skip it for Alcantara, suede, or suede-effect synthetic upholstery · the solvent carrier is incompatible with delicate napped fabrics, and the aerosol format makes controlled application difficult. The DANGER signal word and enclosed-cabin inhalation risk also mean this is not the right product for anyone who cannot spray with doors fully open.
The SDS (3M Document Group 41-2291-7, version 5.04, 2026-05-06) carries a DANGER signal word. The primary health classifications are H370 (damage to organs · cardiovascular system, STOT SE Cat 1) from the aerosol propellant and H304 (aspiration hazard Cat 1) from the carrier · the SDS physician note in §4 warns against sympathomimetic drugs after exposure, indicating cardiac sensitization risk is a documented concern tied to aerosol propellant inhalation. H336 (drowsiness or dizziness, STOT SE Cat 3) also appears. If swallowed, do not induce vomiting · the aspiration hazard classification means forcing vomiting can cause product to enter the airway; seek immediate medical attention. California Prop 65 warning is present; the basis is benzene trace in the petroleum distillate carrier (SDS §13 RCRA D018 classification). The current formula contains no PFAS · SDS §3 lists no fluoropolymer or fluorotelomer ingredients. VOC is high (~714 g/L from the carrier and aerosol propellant) and no aquatic toxicity H-codes appear in SDS §2, placing environment at Notable Concerns primarily due to the high VOC content.
No. The current formulation (3M SDS Document Group 41-2291-7, version 5.04, dated May 2026) lists hydrotreated light petroleum distillates (60·70%), liquefied petroleum gas propellant (20·30%), a proprietary silicone mixture, a proprietary resin, and a proprietary crosslinker · no fluoropolymer or fluorotelomer ingredients appear in Section 3. 3M announced the elimination of PFAS from Scotchgard products and completed the transition. If you're working from an older bottle with an older SDS, chemistry may differ.
The California Proposition 65 warning on the current formula is associated with the hydrotreated light petroleum distillate carrier (CAS 64742-47-8). Petroleum-derived hydrocarbon solvents can contain trace benzene, which is a listed Prop 65 carcinogen. The SDS designates this product as EPA RCRA D018 (benzene) for waste disposal purposes, consistent with the Prop 65 flag. The warning does not indicate PFAS content.
The manufacturer label states reapplication every cleaning or every six months. Independent owners typically report noticeable bead-test degradation at 4·6 weeks on a daily driver with regular vacuuming, which is roughly consistent with quarterly reapplication (not biannual). Heavy use, passenger contact, and frequent vacuuming accelerate depletion. The protection window on car carpet, which sees less direct contact, tends to hold slightly longer than on seat fabric.
No. Scotchgard Auto Fabric & Carpet Water Shield is not recommended for Alcantara, suede, or suede-effect synthetic fabrics. The aerosol solvent carrier can affect the delicate nap structure and finish of napped fabrics. Manufacturer guidance and detailing community experience both flag compatibility concerns with these materials. Use a product specifically formulated for Alcantara or suede · typically a water-based formula applied with a brush applicator rather than an aerosol spray.
The SDS carries a DANGER signal word and specifies: 'Do not use in a confined area with minimal air exchange.' The SDS also includes a physician note about cardiac sensitization risk from the aerosol propellant. Apply with all vehicle doors open and allow to dry before occupying the cabin. The SDS specifies use 'only outdoors or in a well-ventilated area.' If swallowed, do not induce vomiting · the aspiration hazard classification means forcing vomiting can cause product to enter the airway. Seek immediate medical attention.
