How it compares
Compared to built-in wiper fluid additives, the concentrated Rain-X Glass Water Repellent creates a much stronger and longer-lasting bond. It is a completely vegan alternative to glass waxes that sometimes incorporate stearic acids from animal fats.
How to use it
- Clean and dry the glass surface thoroughly.
- Apply Rain-X to a small, folded, dry cloth.
- Wipe onto the exterior glass using a firm, circular, and overlapping motion.
- Allow the product to dry until a slight haze appears.
- Remove the haze with a final wipe using a dry cloth or by sprinkling with water and wiping with a paper towel.

Sustainability & ethics
Rain-X is a cruelty-free brand that does not test its glass treatments on animals. The packaging is made of PET plastic which is highly recyclable in most US municipal systems.
Pro tip
Apply a second coat to ensure complete coverage, especially on larger SUV windshields, to prevent any 'dead spots' where water might cling.
