Rain-X -20F 2-In-1 All-Season Washer Fluid

I use this year-round. It does help with the windshield not streaking and keeping it crystal clear. During Winter it does help melt ice off the windshield. If I hurry and use it after a bug hits the windshield it pretty much gets rid of the mess. Though sometimes it doesn't. It hasn't clogged the windshield fluid reservoir or been slimy on the windshield. I try not to mix windshield cleaners and just stick with this one. There is one that I did try, which is Rain X, and it is pink in color. That streaked my windshield terribly. I won't use it again. For me, this one is worth buying.

Finally I can buy this in California. Although California Bay Area does not have snow in the winter, sometimes temperature goes so low that ice sticks on my vehicle's windshield. This all-year around windshield wiper fluid helps me in that regard. It provides all-year protection and great cleaning power. It makes it more convenient and money-saving to just purchase one thing for both summer and winter.
