Making Your Own Windshield Washer Fluid
With 3 cars, we have to keep 3 windshield washer reservoirs filled during the winter months. I used to see a gallon of fluid for only 99 cents, but now I can’t seem to find it anywhere for under $7. Therefore, I made it my mission to find a recipe for my own washer fluid that is still safe to use in my vehicle. I don’t want something that will corrode or deteriorate the fluid lines or spray nozzles, so I’m careful about the acidic nature of some recipes.
Note: the reason you have to use a “special solution” rather than just water is because the solution has chemicals that prevent the fluid from freezing in the lines. You can’t just put regular water in there, at least in the cold months.
When I Googled for a recipe, I found that eHow.com has a 3-step process. You basically mix water with window cleaning concentrate. However, it doesn’t calculate the costs of using window cleaner vs just buying the stuff at a car parts store.
So you won’t have to navigate over to eHow, here basically what the recipe is.
You need: distilled water, windshield wiper fluid concentrate, a funnel and a big jug to hold everything in. You:
1) You pour the water into the jug
2) Add the concentrate
3) Close the jug and mix everything together really well
4) Put it your car’s reservoir tank.
You need the concentrate because most washer fluid has methanol, ethylene glycol or detergents in them. These additives keeps the washer fluid from freezing and helps it clean.
Many of the other results were just variations of the same ehow recipe, so if any of you make your own fluid, please comment with your recipe, your results and your cost breakdown!
