I don’t know about you, but I tire of getting gouged for simple, and what should be inexpensive things (Bottled water comes to mind). Same goes for Wiper Fluid. If you’ve ever been on the road and run out, you might pay $5.00 for a cheap bottle of washer fluid. It’s Highway Robbery!
You can make your own windshield washer fluid. Why spend $2-$5 on a gallon of washer fluid? It’s easy to make your own. I’m a DIY kind of guy when it comes to this.
The simple and Do It Yourself as you YETI ONE GALLON go way is to at the very minimum carry 2-3 bottles of rubbing alcohol with you that you pick up from a dollar store. If you live some place where in the winter, you’re fighting to keep your windows clean due to the snow etc, you’ll need to do this. – Of Course if you live in a warmer sunny location where freezing isn’t a problem, not so much. Half a bottle of Rubbing Alcohol to a gallon would be fine in the summer.
I’ll put 1 12 oz bottle in a gallon jug. (yes, the old $3.00 jug will definitely work for this, why not? You paid for it!) A few squirts of dish soap, about a tablespoons worth.
And you’re good to go. You CAN add or make variations to this concoction, such as add a couple of cups of white vinegar to it to help remove hard water crustiness, if you have that issue.
Two other ingredients that I’ve heard use, but have not personally tried is to add about 2% anti-freeze to the solution to prevent freezing in the REAL cold areas, such as -30F or so. And 12 oz of Ammonia. – I can’t stand the smell of ammonia, so I’ll pass.
