windshield wiper fluid in winter

Dec 10, 2008 7 Replies

I have been told that windshield wiper fluid used in winter should have anti-freeze in it. Is this true? If one uses regular fluid, how much anti-freeze should one add? I have anti-freeze that is not diluted and must have 50% water added to it



please advise thanks


It depends on where you live and hence how cold it gets. You can buy antifreeze window washer at any autoparts store, don't just pour engine antifreeze in it.

A troll right, ok daffy, Alcohol is its antifreeze, I get a gallon of denatured alcohol and add more, the coolant system antifreeze is for you to drink to keep up Darwins standings.

Hi "daffy",

I hope the "anti-freeze" which you're considering using in the windshield washer is not *coolant* antifreeze. This contains Ethylene Glycol which is not good for the paintwork. The "50%" figure you refer to makes me suspicious because that is the usual ratio for *coolant* anti-freeze.

Windshield washer fluid for Winter use consists of Methyl Alcohol (Methanol) diluted with water.

Take care. Andy I.

Should we tell him about changing the air in tires from summer air to winter air ??

come on now, the guy just needs some advice. most windshield washer fluid is rated at different temperatures. go to your local auto parts store and check out the different kinds they have. But dont pour engine antifreeze into your windshield washer fluid.

No, you should not use engine antifreeze in your windshield washer. You'll likely not be able to see outside.

You need winter blend windshield washer fluid (de-icers), such as:

I guess in the US these lower temp ones are called de-icers and in Europe "windshield washer antifreeze"?
