how often to replace wiper blades

The frequency with which you should replace your car’s wiper blades varies according to different sources and depends on several factors:
General advice: Most experts recommend replacing wiper blades every six to twelve months. This advice applies to regular rubber wiper blades, which have a relatively short lifespan.
Material and weather conditions: The material a wiper blade is made of and the weather conditions it is exposed to also affect its lifespan. For example, heat-resistant rubber wiper blades will last longer, while silicone wiper blades will last the longest, possibly more than a year even with frequent use. However, silicone wiper blades are also more expensive than regular rubber wiper blades.
Symptoms: Wiper blades should be replaced if they show any of the following symptoms: they leave water marks on the windshield, they make a noticeable squeaking sound when used, the rubber part cracks or splits, or the wiper blade skips over certain parts of the windshield when in operation.
In general, how often you should replace wiper blades depends on a variety of factors, including the type of material, the frequency of use, and local weather conditions. It is recommended to check the condition of wiper blades regularly and replace them promptly if any of the above symptoms occur.
