I hardly had to use my wipers. Greatly improved invisibility.

This Rainex additive for use in windshield washer tanks is the best way to keep your windshield waxed. This product is not only obviously easier to use, but leaves less streaks than Rainex wash/wax 2in1 products. I would also recommend first time users to use the Rainex wax spray to manually treat the glass as directed on its bottle. This is worth the effort for glass so slick that water beads and flys off the car, without even having to use your wipers in a moderate rain.

I live in a rainy tornado Gulh Coast area. I need my windshield clear I’ve tried all kinds of wipers but it’s the Rainex that does it The concentrate is small and stows away in the trunk
Product worked perfectly just what I needed. Staff was fine.
The Rain X additive works pretty well and tastes like it's not from concentrate. No bitter aftertaste.
This makes about 3 gallons of washer fluid for half the price of regular one gallon.
Dang ole best stuff out there, mane! I took my wipers off my truck this stuff works so well!
Have been using RainX for decades now. Still the same. I typically apply 3 'coats', then wipe clear with clean paper towel. Lasts about 6 weeks to 2 months, depending on how much rain we get.**AVOID the aerosol version - it is harder to get good coverage because it evaporates too quickly.
Works great! Just add 4oz to your washer fluid tank and go. Works with any brand washer fluid. Just operate your windshield washer / wiper function in your vehicle to spray a little on your windshield and watch the rain roll off while driving. Leaves a much clearer view of the road when raining as well over not using this product.
