The issues with windscreen wipers are well documented. They are getting better with software updates but mine still sometimes fail to come on when it’s raining and wipe away like crazy when it’s dry. The problem with wipers operating when it’s dry is that they just smear gunk all over the screen, and in winter with gritting and what have you there’s a lot of gunk around. I now seem to be totally unable to get the screen completely clean and smear free, which is irritating when I’m driving. Does anyone have any recommendations for cleaning products that could help? Thanks!
