If you leave your De-icer on the car, you might find that it sprays out rather weak, and you don’t get much coverage, it is because the can has gotten too cold overnight and it had affected the pressure inside it.
We know its quicker to leave it in the car, but it actually isn’t. You will use more de-icer, it will take you longer to clear the car and it will run out quicker.
I keep one can in the car and one it the house and swap them around.
How do I know, been there done that.
