How do you get water spots off glass windows?

spit.

try using newspaper to polish, just dry. no water or windex.

Alcohol in a spray bottle and newspapers.

Alcohol and water for scrubbing first.

The only way to eliminate drops and streaks is to use a professional squeegee and lots of elbow grease. I just paid a guy a huge amount of money to remove streaks caused by salt I had put down on the deck above to remove the ice dams.

These come with a long wooden pole for tall windows.

Slightly damp newspaper should do the trick. It’s got something to do with the ink used in the printing. I use this for car windshields all the time.

There is a product for windshields, Rainx, that I use, it takes water spots off and keeps them from forming again. I live in a mountain area with lots of fog, mist and rain, it keeps my windows clear so I can see in these conditions. I started using it on my window at home, they look great.
