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.
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 serious eye damage or eye irritation classification confirmed from the SDS. The DANGER signal word comes from an aspiration hazard and flammability, not from an eye-hazard code. Eye protection is appropriate when spraying overhead where aerosol mist can fall into the eyes.”

From the manufacturer’s Safety Data Sheet, Section 8

From the manufacturer’s Safety Data Sheet, Section 8
“No respiratory irritation classification in the SDS. This aerosol carries a petroleum-based carrier and hydrocarbon propellants with an estimated 540 g/L combined VOC. Use outdoors or with the garage door open · aerosol VOC concentrates quickly in enclosed spaces.”

TL;DR Stops squeaks and friction on rubber and plastic, well-reviewed by owners for mold-release and general lubrication. All community evidence is from craft and industrial use, not automotive door seals, so expect average quality scores for the automotive use case. DANGER-labeled from a swallowing hazard, not a respiratory one. Use outdoors given the high-VOC aerosol propellant.
Sprayway SW946 is an industrial silicone spray built for mold release, dye lubrication, and friction reduction on rubber and plastic. Well-reviewed by owners, it works cleanly in those applications with no staining or residue complaints. No automotive door-seal or weatherstripping reviews appear in the community data, so performance on car rubber is unverified. No directional straw is included. Keep it off painted panels and areas that may need bodywork · silicone residue prevents primer and paint from bonding.
Car owners willing to use an industrial product on automotive rubber without confirmed compatibility data. Skip it if you need verified EPDM seal compatibility. Never apply near brake components; use white lithium grease for metal-on-metal surfaces and penetrating oil for seized fasteners.
DANGER from ingestion only · petroleum-based carrier can cause lung damage if swallowed; do not induce vomiting. No respiratory or eye irritation classified. High-VOC aerosol (~540 g/L); use outdoors. The silicone film stays on the surface and does not run off into drains.
The Safety Data Sheet for Sprayway SW946 Silicone Spray and Release Agent carries a DANGER signal word, with classified hazards including H222 (extremely flammable aerosol); H229 (pressurized container: may burst if heated); H304 (may be fatal if swallowed and enters airways). See the PPE breakdown above for use-case-specific guidance translated from the SDS hazard codes.
CarCareTruth scores Sprayway SW946 Silicone Spray and Release Agent at 5.6 out of 10 on the composite CCT score, with a health sub-score of 5.0/10. 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.
