The wipers on my car have been screeching since I bought it about three years ago. I put new rubbers on them a while back, but that didn’t fix it. I don’t drive in the rain frequently enough for it to be a major bother, but yesterday, I was near a Supercheap Auto, so I went and spent the money on some good quality replacement blades.
They work smoothly and perfectly. After three years of screeching, a silent wipe is almost unfathomably satisfying.
I’m actually in the market fow new wipers and I’ve been using RainX for well over a dacade. Maybe it’s time to try a new brand. My last set of Rain X blades started to leave streaks after like 6 months (could have been the really bad winter - lots of ice and salt). Not horrible streaks, they aren’t a safety concern, but little imperfections really bother me. I’m very particular about my windshield cleanliness.
