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
“Eye irritation is present from the carrier chemistry. SDS §8 specifies safety glasses with side shields or chemical goggles. The DANGER signal word is driven by an ingestion/aspiration pathway (H304), not an eye hazard; the eyes tier is recommended based on the irritation classification, not the signal word.”

From the manufacturer’s Safety Data Sheet, Section 8
“The DANGER signal word is driven by a health-tier H-code (H304 aspiration hazard Cat 1), and skin irritation (H315) is present. Skin protection is required per the rubric escalation rule for DANGER from health H-codes. SDS §8 specifies chemical-resistant gloves for handling.”

This product ranks #2 of 7 in Silicone Lubricant.
Last reviewed July 2, 2026
TL;DR CRC #05174 is the top-selling aerosol silicone lubricant on Amazon; it reliably silences squeaky door seals and sticky window tracks on first application. DANGER-labeled: the petroleum-naphtha carrier warrants wearing nitrile gloves. Keep it entirely off painted surfaces, since silicone contamination prevents paint and primer from bonding.
CRC #05174 is an aerosol silicone lubricant with a directional straw for rubber and plastic maintenance: door seals, weatherstripping, window tracks, sunroof seals, and hinge pivots. Attach the straw and apply a brief burst; the carrier evaporates and leaves a silicone film. It is broadly trusted by owners, who reach for it again and again for consistent performance on the core job, and it is the category best seller in Automotive Assembly Lubricants. Community durability lands in the 4·8 week range on outdoor-exposed seals. Keep it off painted panels and any surface where paint or adhesive bonding is planned; silicone residue prevents primer and paint from adhering.
Best for car owners with squeaky door seals, sticky window channels, or stiff weatherstripping. Skip it for metal-on-metal applications (hinges under load, fasteners, chains); use white lithium grease instead. Never apply near brake components.
DANGER signal word from the petroleum-naphtha carrier's aspiration hazard, a swallowing risk, not an inhalation hazard in normal use. Skin and eye irritation classifications are also present. Wear nitrile gloves and safety glasses. Use outdoors or with ventilation in enclosed garages. Carries a California Prop 65 warning for cancer and reproductive harm from trace petroleum impurities. CARB-compliant. Aquatic toxicity is classified; keep away from drains.
Safe for brief and normal-use contact with EPDM and neoprene rubber seals; no documented rubber degradation in community reviews. However, the formula uses a petroleum-naphtha carrier, not a pure silicone-oil base, so surface_safety is scored conservatively (6/10). Prolonged or soaking contact with rubber is not the intended use and is not recommended. For a pure silicone-oil formula with no petroleum carrier, look for products whose SDS Section 3 shows only PDMS and propellant.
The DANGER label is driven by the aspiration hazard classification (the spray may be fatal if swallowed and enters the airways), an ingestion pathway, not an inhalation hazard in normal use. Extreme flammability (H222) also contributes. The carrier is petroleum-naphtha, which carries this classification. For a home detailer applying the spray to door seals or window tracks, the practical risk is: don't ingest it, keep it away from ignition sources, and wear gloves.
Yes. The product carries the California Proposition 65 warning for Cancer and Reproductive Harm. SDS §15 (2024 revision) lists trace impurities in the petroleum-naphtha fraction including benzene, ethylbenzene, naphthalene, acetaldehyde, cumene, and toluene; present at concentrations below ingredient-disclosure thresholds in the formulated product but at levels that trigger the mandatory Prop 65 label. This is common for petroleum-carrier aerosol products.
No. Keep silicone spray off all painted surfaces, primer, or any area that may need touch-up paint or body panel adhesive bonding. Silicone residue is very difficult to fully degrease and prevents paint and primer from adhering, a known issue in body shop work. Apply only to rubber seals, plastic trim, weatherstripping, window tracks, and hinge pivot points.
Yes. SDS §15 states 'This product is regulated as a Silicone Based Multi-Purpose Lubricant. This product is compliant for use in all 50 states.' The CARB compliance reflects VOC accounting under that product category's regulatory limits. Absolute VOC emissions (estimated ~411 g/L) remain in the high-VOC bracket; the product is compliant, but aerosol VOC is still substantial.
