Rain X 2-in-1 Glass Cleaner + Rain Repellent Review

  • Cleaning Rating: 5/10
  • Rain Repellent Rating: 9/10
  • Ease of Use: Medium
  • Scent: None
  • Where to buy: Amazon

Rain X Glass Cleaner and Rain Repellent cleans automotive glass. The layer it leaves behind causes water to bead and helps prevent snow, ice, and bugs from sticking to your windshield.

Use on exterior auto glass. Only use in well-ventilated areas.

Directions: Spray the product on the glass in small sections. Wipe away with a clean towel to remove dirt and grime. Wipe with the dry side of the towel to leave a streak-free water-beading coating. Allow at least an hour before exposure to rain or water.

How We Tested Rain X Glass Cleaner and Rain Repellent

I used Rain X on my windshield to test how well it works. I had mixed results.

I started by spraying half of my windshield with the product and wiping it off. Besides removing a layer of dust, you couldn’t tell which side of my car I’d cleaned. So I reapplied in smaller sections trying to scrub off dirt and splatters. It took a lot of elbow grease, and still no luck on some spots.

Here’s the good news: this product does repel moisture. I dumped water on both sides of my windshield, and it’s easy to tell which side I treated.

How We Tested Rain X Glass Cleaner and Rain Repellent

RainX helps repel water and is something I’ll use a lot during the winter months. But next time, I’ll clean my windshield with my homemade glass cleaner a day before using this.

Pros and Cons of Rain X 2-in-1 Glass Cleaner

Here’s what to consider before trying Rain X 2-in-1:


  • Excellent at repelling water
  • Easy to use
  • No harsh smells
  • Can reapply as needed


  • It doesn’t clean well
  • It contains acetone and is flammable
  • Only intended for exterior car windows – while some people love to use this on their glass shower doors, the bottle cautions against using it on surfaces other than intended. But you can buy a shower door product from Rain X.

Who This Product is For

Use this product if you have a hard time seeing through rain and snow. But I recommend using a different product to clean your windshield before applying Rain X.
