Avoid using harsh chemicals or abrasive cleaners, as these can leave streaks or damage the window. Use the right type of cloth or sponge: A microfiber cloth or a squeegee is generally the best choice for
Use vinegar solution and clean the surface using a microfiber cloth. See whether it works or not. Spray rubbing alcohol ( diluted in water in a 1:1 ratio) on the streaks and try to wipe them with a clean cloth. Adjust the cleaning direction from circular motion to horizontal motion and apply any streak free cloths.
A big problem is the evaporation rate. If you're cleaning your windows on a warm sunny day, the liquid part of the solution evaporates quickly and leaves behind a residue that appears as streaks. On the other hand, if you don't entirely remove the liquid you can also be left with a streaky window.
First lightly mist the window with Windex, dry with one clean rag. Once dry put some rubbing alcohol (100 proof vodka works as well) on the other rag and wipe the window down until dry. Take a dry cloth and polish any streaks away. Doesn't take long and works a treat. This also works on mirrors around the house.
Try vinegar for hazy windows: For hazy or cloudy windows, mix equal parts of white vinegar and water in a spray bottle. Spray the solution onto the window and wipe with a lint-free cloth in a circular motion. Vinegar helps to cut through the residue and restore clarity.
Using Space Heaters & Hairdryers. Space heaters and hair dryers are products that are in almost any home and these can be used to help clear the condensation from your double pane windows. Place the space heater or hairdryer by the window and leave it on. This will absorb all the moisture in between the windows.
To eliminate streaking, make sure the vehicle is in the shade and the window is cool. The towel you clean with should be lint and oil free. A lot of car washes use microfiber, but any soft cloth or chamois will work, as long as it's clean.
Thankfully, correcting windshield haze is easy. All it takes is the application of a quality streak-free glass cleaner and horizontal passes with a microfiber cloth or windshield cleaning tool. Apply an anti-fog solution to the windshield after cleaning for the best results.
Another common cause of streaks is using a dirty towel or rag to clean the glass. If the towel is covered in dust or other debris, it will likely just smear these particles around, leaving behind streaks. Be sure to use a clean, soft cloth when cleaning your windshield.
The best solution is simple a homemade mixture of warm dish soap and water. More cleaning solution does not equal a cleaner surface. In fact, over using cleaning solution is one of the main causes of a streaky window. Paper towels leave behind streaks and fibers but good old fashioned newspapers do not.
White marks on a car windshield are often caused by a variety of factors, including mineral deposits, hard water stains, or other contaminants. Here's how you can try to remove white marks from a car windshield: Vinegar Solution: Mix equal parts of distilled white vinegar and water in a spray bottle.
Direct Sunlight Causes Water To Evaporate Faster
The reason that windows are more prone to streaks when cleaned in direct sunlight is that the extra-warm glass causes the water to evaporate more quickly. As such, a film of soap or detergent can be left on the glass where the cleaning solution has dried too quickly.
And while ammonia-based cleaners like Windex are known for their cleaning power, the smell isn't so great. Plus, ammonia can leave streaks and film on some types of windows. But not to worry, CR found that the ammonia-free options cleaned just as well. The winner was Sprayway Foaming Glass Cleaner.
Spray a stronger mix of 1:1 water and vinegar (or Windex, or glass cleaner) at your window, so that the solution covers most of the glass. (I found Windex to work better, but if you have pets—or kids—who frequently lick outdoor windows, vinegar may be the best route for you.)
After cleaning your windows with hard water, the water evaporates and the mineral deposits are left behind. The result is a cloudy, chalky look on the glass, white spots, or an almost moldy look.
“Use microfiber cloths to wipe the inside of the glass in a circular motion, then vertically. Next, use a magic eraser with water, using the same method. Lastly, spray glass cleaner on a microfiber cloth and wipe to finish.”
You can use a solution of equal parts water and white vinegar to solve this problem. Apply it to the glass, let it set for a little while, and then scrape or squeegee the surface to get rid of the streaks and mineral deposits.
Ditch the paper towels—they're scratchy and leave fibers behind. Waffle weave microfiber towels are your streak-free, dirt-trapping best friends. Stick with ammonia-free, glass-specific cleaners.
If you live in an area of hard water you may end up noticing more streaks than before. Hard water contains high mineral content, including fluoride and calcium. If you do happen to live in a hard water area, it is a good idea to use distilled water that you have warmed in the microwave before use.
One of the most common reasons for glass to become foggy or cloudy is water damage. This can be from a leaky window, condensation, or even humidity in the air. When the seals at the bottom sit in water they can deteriorate and the seal can be damaged.
A common result of moisture damage, discoloration typically appears as black or dark-colored streaks on the surface of double-pane windows. It may not feel wet to the touch, but it is a telltale sign of excessive moisture inside the home.
Turn the heat on its maximum setting, because hot air can hold more moisture. Turn the AC on, which will pull the moisture from the air as it passes over the cooling coils. Turn off the recirculation button, so colder, dryer air is brought into the car.
