If the blades show signs of cracks, chips or any defects your eye can see then they’ll have to be replaced – WD-40® does not perform miracles!
However, if all looks fine but the rubber feels old and staid then WD-40® can possibly help. Preferably, the experts suggest using WD-40® Specialist Silicone Lubricant to resolve the issue of under-performing blades. Simply soak a cloth in solution, pull your wipers up and then liberally and thoroughly clean the wiper blades and then leave upright to dry for a couple of minutes and then re-sit into place. Silicone is known to rejuvenate rubber and even slow down the aging process.
