From the manufacturer’s Safety Data Sheet, Section 8
“The DANGER signal word is driven by an aspiration/swallowing hazard classification — an ingestion pathway with no eye-contact relevance. SDS §2 carries no eye irritation or serious eye damage code. Eyes protection is situational: use safety glasses when spraying overhead or into confined gaps where misting can reach the face.”

CarCareTruth's Analysis
Last reviewed May 16, 2026
Reliable at silencing door seal squeak and sticky window tracks — community confirms 4–8 weeks on outdoor rubber. The permanently attached Smart Straw flips stream or fan, which earns its keep in tight hinge gaps. Keep it off painted panels; silicone residue prevents primer and paint from adhering.
What it is and how it performs
An aerosol silicone lubricant for rubber seals, weatherstripping, window channels, and plastic trim slides. The permanently attached Smart Straw flips between a focused stream and a wide fan spray — the petroleum-based carrier solvent delivers the silicone film, then evaporates. Community data from 21,025 reviews confirms first-application success on door seal squeak and window track binding, with 4–8 weeks durability under outdoor exposure.
Keep it off paintable surfaces: silicone residue is difficult to degrease and will prevent primer and touch-up paint from bonding.
Who should buy — and who should skip it
Best for squeaky door seals, sticky window tracks, and rubber weatherstripping. Skip it for metal-on-metal contact (load-bearing hinges, fasteners, chains) — white lithium grease is the right tool. Never apply near brake rotors, drums, or pads.
Safety and environmental impact
DANGER signal word from an aspiration hazard classification — swallowing risk, not inhalation in normal use. No respiratory irritation code is present at the mixture level. The petroleum solvent carrier warrants gloves for extended work; eye protection for overhead or misting-spray situations. Spray outdoors or with the car door open. CARB compliant, no Prop 65 warning required per the 2024 SDS.
