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.

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.

TL;DR Community durability runs 2·4 weeks on a daily driver; independent highway sheeting data is not available, though the Rain-X community broadly reports sheeting sufficient to run without wipers at highway speed. Signal word is DANGER (H304 aspiration hazard from LPG propellant, H222 flammable aerosol) · apply outdoors or with the garage door open.
This 18 oz aerosol deposits a water-beading layer on automotive glass in a single spray-and-wipe pass · no separate cleaning step, no buffing timing to manage. The aerosol format eliminates the drip problem of pump-trigger versions and makes side windows and rear glass easy to cover. Community durability is honest for a convenience 2-in-1: expect 2·4 weeks of beading on a regularly washed daily driver. This is a between-applications maintenance product, not a durability rival to standalone Rain-X Original or a bonded glass coating.
The right buyer wants clean glass and basic rain protection in under two minutes at a low price. Skip it if you want durability past a month · Rain-X Original or a bonded coating like Aquapel lasts materially longer per application. Also skip it for interior glass: the label explicitly states this product is not intended for interior use.
DANGER signal word is driven by H304 (aspiration toxicity Cat 1 · a swallowing hazard from the LPG propellant, not an inhalation classification) and flammable aerosol (H222, H229). SDS §2 does not classify H319 or H335 · the eye and skin PPE language in SDS §8 is precautionary. A Prop 65 reproductive-harm warning is printed on the physical can; estimated VOC is low (~40·60 g/L) and no aquatic toxicity is classified.
The Safety Data Sheet for Rain-X 2-in-1 Glass Cleaner Plus Rain Repellent (Aerosol) carries a DANGER signal word, with classified hazards including H304 (may be fatal if swallowed and enters airways); H222 (extremely flammable aerosol); H229 (pressurized container: may burst if heated). The Amazon listing also carries a California Prop 65 warning. See the PPE breakdown above for use-case-specific guidance translated from the SDS hazard codes.
CarCareTruth scores Rain-X 2-in-1 Glass Cleaner Plus Rain Repellent (Aerosol) at 6.2 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.
Per the Safety Data Sheet ingredient disclosure: Water (60·100%), Acetone (3·7%), Liquefied Petroleum Gas (1·5%)
