How often should you replace your car's wiper blades?

It is generally recommended to replace your car's wiper blades at least once a year. However, the frequency at which you need to replace them may vary depending on various factors such as the climate you are in, the quality of the blades, and how often they are used. If you notice any deterioration in their performance, such as streaking, smearing, or skipping, it is a good indication that it's time for a replacement regardless of the time frame.
