If a wiper blade squawks as it moves across the windshield, does that mean that the rubber is hardening and it will soon be no good? Or can they last for months/years like this?
I just started hearing a squawk this week, from a blade that I installed in March (RainX Expert Fit conventional). My first guess was that the rubber was hardening and should be replaced, but then I searched online and found a lot of folks suggesting to simply clean it. RainX says to wipe the blade when you wash the car, with the soap, but I am wondering if squawking blades can last a long time in this state or not. I'd rather not use a blade just cuz it works, if the hardened rubber is going to scratch my windshield.
