Washer fluid

(1/2) > >>

Hurricane:
Bought some washer fluid today. Led me to wonder how to make my own. What do you add besides water? I would think that dish soap might not last that long, compared to commercial products. Straight Windex could get expensive.
In my area, I'm not worried about freezing.

Redman:
Here are 4 ways I found. I didn't read them thoroughly just skimmed though.

Last ww fluid I bought I paid less than a $1 per gallon at WM. That's been several years ago.

thechemist:
The blue fluid is typically made with methanol. I'm not sure where you could easily get some methanol to make it. For myself, I used to work in a lab that had lots of excess, expired methanol that I was allowed to take home. 

NWPilgrim:
Methanol is readily available. Most of the gas “heet” treatments are methonal. Also look in paint supply departments. But you can use any alcohol such as isopropyl. A 70%/30% blend of iso/water is both lowered freezing temp and a decent cleaner of bio material like bug splats. Also good in a spray bottle to “melt” icy windshields and windows when you go out to start the vehicle in the morning.

Mr. Bill:
I found out 40 years ago that making my own windshield washer fluid with ammonia is a good way to destroy the pump.

Of course, that was so long ago that the pump was a squeeze-thing that you pumped with your left foot. 8)  I don't know what modern pumps will tolerate.
