I noticed the local big box store had a big display of blue windshield washer fluid for cheap. I was about to load up for winter and noticed it said +32 formula. Here in the upper Midwest it is likely we will see freezing nights beginning in the next few weeks.
I passed in the “deal” but remembered I had a jug or two in the garage and thought I better check them out. Sure enough, I had summer fluid. I don’t really ever remember seeing summer washer fluid except those specialty bug washer or rain-x stuff, not the basic blue. So double check your fluid the next time you buy if you are in a cold climate. Nothing is worse than frozen washer fluid when you have salt accumulating on the windshield.
