How often to change winshield wipers?
There’s no rule on how often to change wiper blades. While blades usually last between 6 months and a year, the type of wiper, the type of blade, and the weather affect the life span of your blades. If your blades leave water behind, or they skip, even when the window is wet, it’s time for a replacement.
What affects blade life? Extreme heat and cold accelerates aging, as does exposure to UV light. Traditional wiper frames put added pressure on the blade at the frame’s joints, distorting the blade over time. This leads to blade skipping and streaking. Rubber blades age faster than silicone blades.
