Switch to silicone rubber wiper blades. They cost more but last 3 times as long. All I use on the buggies and the tractors.My old ford 3000 we put tubes In tires and loaded tubes with calcium chloride mixture. May do that to my kubota too we will see after winter. But I would say windshield washer fluid is no better. It rots winter wiper blades. Cracks them. But either way I think if you load tires it will cost you to do it and cost you again to repair it later. It's a vicious cycle of life.
