An elderly lady in my building asked me a question that she says is a silly one...but I don't think is silly at all.
No, it has nothing to do with god but with filling up her windshields whippers'tank with 3/4 of vinegar and 1/4 of water. Her rationale behind this question is "If vinegar cleans my windows to perfection...why can't I use vinegar to clean my car's main window? " 
Answers, please.
Actually the answer is, it depends. Vinegar and water will freeze. If it freezes in the car's windshield washer tank it might break the tank. On the other hand, if you live where it doesn't freeze that wouldn't be an issue.

                                        We are in New York....that's why I asked all of you about mixing the vinegar with the regular fluid. She parks on the streets and that is what creates the big problem....I see her cleaning that window every day.
@DUCHESSA Definitely don't do it then!! I put vinegar and water in a spray bottle to use on my windshield and it froze solid. There's a Preston de-icer that's really good though.
@sewchick57 I guess she will have to use the vinegar only during the summer.
She sounds like she needs a(nother) hobby.

                                        Well, it sounds you didn't read the other members' posts.
Please don't think I'm making fun; I'm not, but do you call them "windshield WHIPPERS" where you live? It's kind of making me laugh. We say "wipers" where I live but I kind of like the sounds of whippers. pasha-one-nine

MIght want to google what vinegar does to car paint, and I do not know. The gallon bottle of car wiper fluid it cheap, spring a few bucks to save the paint.

                                        She wants crystal clear windows. BTW, I get the whippers for a dollar and so does she.
Yup. Vinegar is acidic (though just how acidic dilute vinegar in water is, is another matter.) I've used neat vinegar to get lime residue off my car bodywork before now (underground car park, that was dripping something from the concrete ceiling onto the cars.) No ill effects there, but I still don't think it's sensible to expose your car paintwork to it without good reason.
