Speaking of windshield washer antifreeze solution, I go into WallyWorld to pick up a gallon of that blue cheap stuff that used to be $1. There is about 25 feet of windshield washer fluid in every color you can imagine and with about every feature washer fluid can accomplish. Remove bugs! $4.95, Clear haze!, $3.99, RainEX! $5.99, etc. BUT NOT ONE bottle that did not say “Summer Formula” for over 32º. Now what is this about? Some of that stuff is bound to be in the washer tank when we fly back in January for our month of winter and I expect it will be frozen solid! If I want Summer formula it will be WATER!
It works really well for just a little while. Then it EATS the rubber on the wiper blades. With premium wiper blades running well over $20 each now a days, saving money on home made washer fluid can get really expensive.
I tried this a couple times and the blades started smearing rubber onto the windshield. Had to clean it off with plastic polish!
