Screenwash or no screenwash

[Opensauce]

I always get screenwash from French supermkt on my day trip Calais beer run. 3€ for 5litres of -15C is good value, I always dilute with about half water if really cold. Never had it freeze yet. Trying to use washers when frozen can blow fuse, I think.

Always used halfords berry blast screenwash with no issues, it's good for down to -10 smells nice and it's just been on offer at half price at 5ltrs for £2.49.
