Yes. We would certainly recommend a suitably diluted screen wash or anti-freeze additive in the water reservoir.
Allowing water to freeze in the water reservoir can cause the bottle to crack, just like on your car screen washer reservoir. Check the manufacturers recommendations for details of the dilution.
Always ensure you label the water reservoir correctly to reflect the use of poisonous substance.
