Question

DentroTest · Accepted Answer

Keeping the windshield wiper blades in good condition is essential to ensure adequate visibility in adverse weather conditions such as rain, snow or hail. Over time, with exposure to the sun and to extreme temperatures, the rubber dries out, hardens and cracks, losing its flexibility and its ability to clear water effectively. It must be replaced immediately when this deterioration is noticed, since faulty wiping compromises safety and can scratch the windshield. There is no fixed regulatory interval of six months, nor should you wait until they break completely before changing them.
