Hope this has not been covered elsewhere in these forums.
I've got a late-2018 model 3, and am located in Vancouver BC. We have reasonable amounts of rain, so wiper functionality/good rain visibility is (obviously) important. I'm having difficulty seeing through the windshield in heavy rain though, and it doesn't seem that I can clean away whatever problem I'm having. There is an obvious difference between the sections of the windshield that are covered by the wipers, and the sections that are not. Water beads easily on the non-wiped sections, and on the windows, roof, rear glass, etc., but water does not bead at all on the wiped sections. This requires full speed wiping for even moderate rain, which leads to another issue: what look like hard water stains (faint slightly opaque spots) show up on the windshield momentarily when the wipers are operating at high speed.
I tried washing the window with regular car wash (Meguier's something), household vinegar, dish soap, Windex, and none have made any difference at all.
I've attached some photos below where the clear difference is apparent. I also have a video of hose water spraying ont the windshield, showing the difference in beading/coating - (
)
What is the problem here? Have I somehow used the worst wiper fluid in existence and built up an indestructible coating of water-attracting junk? Is it a windshield issue? A colleague has suggested Rain-X. but I've seen all of the posts regarding Rain-X and Tesla, so don't want to go down that route if possible. I need a solution, though...
