I used to use Rain X spray on my previous vehicle but stopped once I got a wrangler after I noticed that it caused smearing. Since then, I’ve just been getting good quality blades and glass cleaner and all has been good since.
also, I replace them every 6 months as well.
It was all around us and a couple of those pictures are looking directly up. I’m so glad that it stopped raining! We had 2 very cloudy and rainy/snowy weeks.
