c-1 wiper fluid

[Susan G.]

Hi, I am just about ready to fire up my wiper and washer system. I live in Canada, I want to know if I can use windshield washer fluid that is for -40 C. Should the system be drained in the fall? Will the fluid hurt the system? Is it better to just use water?

Thanks Susan

Some fluids are harmful to paint so I don't use chemicals in the washer bottles. Maybe a little dishwashing detergent would be ok. I use water and I make sure my blades are clear of any fine abrasive dirt and sand. Nothing worse than scratching a new screen. I'm so anal about scratching my screen I actually don't use my wipers.

Susan- Hi, if you are going to use your windshield washer in below freezing ambient temperatures or store your car in an unheated area, I would definitely use a suitable cleaner/solvent designated for winter usage. I would recommend "Rain X" winter formulation. Have you already tested the washer's operation? I would do any trials of the system in a heated environment simply using water, then if no problems, drain and switch to appropriate washer fluid. In my opinion, keeping the system filled for an extended period shouldn't cause any damage, but I think it might be a good idea to use the washer occasionally even while in storage, also remember that the product will lose some of it's anti-freezing properties over time. Always try to keep fresh product in the system, especially in freezing temps.
