Yes I do mean winter screen wash, it’s still liquid in the washer bottle. I even left the mixture in the container outside during the cold snap and it was still liquid.Maybe I should just us it undiluted in the winter from now on.
I have a 2014 defender and even although I have a strong antifreeze solution in the washer bottle it still freezes, even after pouring hot water over the jet doesn’t cure it. I am guessing there must be somewhere along the pipe that is open to the elements more than the rest.Even after a two hour journey it didn’t defrost.
