Review: Good windshield washerfluid. - Just washer fluid. Works fine I mean what can you say?
Review: Works great, saves money & reduces our plastic consumption - Works exactly as expected. We go through a fair amount of screen was during the winter months, so I was looking for an alternative to the expensive gallon bottles of winter screenwash. We usually go through 5-6 gallons for our cars and so I wanted an option to use less plastic and to save money. I bought a large pack of 100 screenwash tablets for $10 (each one dissolves in a gallon of water) and then I add this product to prevent freezing. Has been fine in temps way below freezing and making my own screenwash probably saves us over $100 a year and saves on 7-8 gallon plastic containers we no longer have to buy. Very happy with this.

### ⭐⭐⭐⭐ It works great if your windshield fluid freezes
*by C***Z on March 19, 2018*

Used it before when the washer fluid froze years ago. AutoZone no longer carried it. Found it on Amazon for more than I did the first time in Autozone. It works great if your windshield fluid freezes. Takes a few hours to work after pouring in.
