Hi, I have tried everything I can find in forums etc to stop my front wipers smearing water. I have replaced the wipers with Denso wipers. Denso manufacture Wiper Blades for Toyota and are exactly the same as my original blades. My wife’s Lexus CT200h has the same blades so I tried them with the same problem. My RAV4 blades on the Lexus are fine, no smearing. i tried A Bosch blade on the drivers side, still smearing. So, I can safely say that it isn’t the blades.  The winds
