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
“H222 (flammable aerosol) and H229 (pressurized container) are present at §2 but no H318 or H319 in the §2 GHS classification · H318 is the only code that drives eyes required. Aerosol form factor creates mist near face; situational with spray_application trigger is appropriate.”

From the manufacturer’s Safety Data Sheet, Section 8

From the manufacturer’s Safety Data Sheet, Section 8
“Aerosol form factor is the primary inhalation risk · fine mist near face and chest during application. No H335 (respiratory irritation) in §2 mixture classification, so tier stays at situational (the aerosol baseline minimum).”

TL;DR DANGER-rated aerosol · wear nitrile gloves and use outdoors or in a well-ventilated space; do not induce vomiting if ingested, seek medical attention immediately. Community-confirmed quiet garage doors for 6·7 months on a single application · the chemistry warrants real precautions, but the performance is the best in the category for residential hardware.
Purpose-built for garage door hinges, tracks, chains, pulleys, and nylon rollers. Spray on, cycle the door a few times, done. Community owners report 6·7 month intervals before reapplication and immediate squeak elimination even after cold-weather failures. The Smart Straw rotates between stream and fan-spray modes and cannot be lost · praised for reaching every component without mess. The silicone additive provides moisture resistance, which is expected for an oil-carrier aerosol.
Right reach for a homeowner who wants quiet, smooth garage doors for most of the year. Skip it in enclosed or poorly ventilated spaces · the aerosol builds up quickly and the DANGER rating is real. Frequent indoor users should choose a pump-spray lubricant.
Rated DANGER from H304 (aspiration hazard) · do not induce vomiting if ingested, seek medical attention. Fine mist from aerosol application creates the primary inhalation exposure. No California Prop 65 per SDS §15. VOC approximately 397 g/L; CARB compliant. Silicone residue can transfer to adjacent paint or glass if over-sprayed. Not confirmed biodegradable (SDS §12 lacks OECD test method).
Community owners consistently report 6·7 months between applications on typical residential garage doors. The silicone additive in the formula contributes to moisture resistance that helps extend the lubrication interval.
Yes · the product is specifically formulated for all garage door components including nylon rollers. The silicone additive is compatible with most rubber and plastic types, and no community owner documented nylon roller damage. However, the petroleum carrier can leave a slight film on adjacent painted surfaces or glass if over-sprayed · wipe overspray promptly.
The DANGER signal word is driven by Aspiration Toxicity Category 1 (H304) · the petroleum carrier can be fatal if swallowed and enters the airways. Do not induce vomiting if ingested; seek medical attention immediately. This is the correct first-aid response for petroleum distillates.
The SDS Section 15 states explicitly: 'This product does not require a California Proposition 65 warning.' the product listing may show a Prop 65 flag · that appears to be Amazon's blanket California disclosure, not a formula-based requirement. The SDS controls for regulatory classification purposes.
The Garage Door Lubricant is an aerosol with a petroleum-distillate carrier plus silicone additive, designed specifically for garage door hardware (hinges, tracks, chains, rollers). The Multi-Purpose Oil is a heavy naphthenic drip-bottle product for stationary indoor mechanisms (hinges, locks, sewing machines). Different formulas, different form factors, different use cases · and a meaningfully different health profile: the aerosol carries a DANGER signal word while the drip oil is Not Hazardous.
