One of the biggest advantages of choosing de-icing wiper fluid is the fact that, most of the time, it can be used year-round. While it will come down to the specific formula of the wiper fluid, there have been users who have gone on record of saying that they have left their de-icing wiper fluid in their vehicle in the summer. The reason most of them will still be sufficient when it comes to removing bugs and residue from your windshield. Plus, if there does happen to be a randomly cold day in the non-winter season you know you will have the best option.
