Your favorite washer fluid

For the warmer half of the year I like Prestone Bug-Wash Washer Fluid. Available at my local Walmart.
For the colder half of the year I like Prestone De-Icer Washer Fluid (-27F).

Walmart used to carry the De-Icer fluid, but stopped about 2 years ago, so I switched to the local NAPA store for it. It appears to be in very short supply at NAPA (and other sources) when I checked this week.
 
Water and a few drops of dawn is all I use in the summer months, works pretty good on bugs etc. Usually rain-x orange in the winter
 
I use the -30F Peak from NAPA and I add a few ounces of 409 cleaner to each gallon. The 409 makes it cut grease and remove oil if it ever gets on your windshield, like if a vehicle going the other way hits a big pothole that had water and some oil in it and it splashes on to your windshield. I use this year round so there is no need to drain in the fall.

Just picked up some distilled water to mix a new batch of the Kristall Klar...great stuff...smells good...not AS good as the VW factory stuff though ;)
 
I just recently started making my own from a recipe found here. 1 Oz Castille soap, 9 Oz isopropyl alcohol, and 118 Oz of distilled water. Add a few drops of blue food coloring and it's very economical and effective!
 
I am happy with just the regular blue -35C (-31F) stuff. When I lived in Alberta I would occasionally use the green -45C (-49F) product if it was on sale. One thing I have not had any luck with are products with additives i.e. bug / de-ice / anti-beading / etc. I just prefer the plain straight up stuff.

No smell..I must have got the dealership Walmart flavor...

I use this in all my cars with the addition of 1/4 cup of ammonia. It works extremely well.
 
Anybody notice the orange Rain-X washer fluid makes your wipers chatter? I had to stop using it due to this. Now it's just whatever -20° blue stuff I can find.
