How long will a Rain‑X ® Original Glass Treatment application last? This product typically lasts about 3 months depending on weather and environmental conditions.

Does Rain-X repel water?

In a simple sense, Rain-X repels water, causing it to bead up and roll off of glass surfaces. By nature, water sticks to glass and spreads out instead of rolling off. Rain-X repels water similarly to the way that oil does, and this causes the H20 to go bye-bye.

Is Rain-X the same as Windex?

There is a rain-x product that is cleaner + repellent in one. It’s basically just windex with rain-x added, kinda like the washer fluid is standard fluid + the additive. But for best results, super clean windows, dried, and then apply repellent on its own.

How effective is Rain-X?
