How do I remove hard water spots from car window?

Spray and Wash... the stuff for laundry stains will take care of that.... it's also great for hard water stains on glass shower doors.... don't even have to scrub!

Very safe, but a bit labor intensive--- Purchase POLISHING compound. It looks like cream cheese and is very gentle on paint and glass. Follow the instructions EXACTLY and do not use excessive pressure. It is safe for the glass as well. DO NOT use RUBBING compound. It looks like terra cotta. This is for a different purpose, and it is much too coarse and harsh for your paint, and will certainly scratch and scar the paint and glass. An option to both is MOTHER"S aluminum polish. This can be used for all sorts of etching in glass and paint. If the marks are just a water spot, usually water & vinegar in a 50 / 50 concentration works well, but won't take out the etching. Good Luck

50/50 mixture of vinegar and windshield washer fluid. Works great on boats. Avoid the WD-40. It will be very hard to remove.

WD-40, then white vinegar and water.

CRC, a solution of vinegar and water, lime away

use fine steel wool and car polish it wont scratch the windows but it will scratch the paint so be careful also lime away will work

Try vineagar and newspaper it's like a polish for windows. But don't use it on tint.
