The residue on the glass can be caused by several sources. For example, an oily film from off-gassing from the interior vinyl dash and cars interior fabrics is caused by the hot sun baking the dash.

Also, smoking leaves an oily residue on everything. The AC and heating systems can also deposit particles on the glass. Always clean the outside of the windshield first. It is much easier to see streaks on the inside when the outside is already clean. This applies to all interior windows.

Here’s a quick video from ChrisFix on cleaning the inside windows:

Follow this steps for a streak-free result

Start by using a microfiber cloth to clean the inside of the windshield. Use a circular motion and then an up and down motion to finish. Change the cloth for a clean one whenever the cloth is dirty.

Avoid allowing the cloth to touch the dash since the cloth will pick up contaminants from the dash and may transfer these contaminants to the glass. You may have to use a back hand method to reach some of the more challenging areas of the windshield.

Next, use a Mr. Clean eraser or alcohol to further clean the glass. If you use alcohol, spray it onto the cloth to avoid dripping onto the dashboard. Again, clean the glass in circular motions followed by up and down motions. Always dry the windshield and do not allow the cleaner your using to dry on the windshield.

Choosing a window cleaner for tinted windows

Desinged for tinted car windows

Everyone has different stories of their search for the best cleaners in the market. There are many types of cleaners, depending on the ingredients used in their manufacture. This variety also diversifies the type of stains they clean in the car window.

Although nowadays most cleaners remove a lot of stains, there are other cleaners that do not remove some stains like oil based stains. A cleaner composed of a mixture of water and vinegar, for example, does not remove oil based stain in a window unless it has an aftermarket tint.

One should choose a good cleaner that suits his/ her taste. You should take your time and read the ingredients before making any purchase. A good cleaner has chemicals that are not harsh and does not leave smudges and streaks on the window.

We found the Shine Society product suitable for both car window tinted and non-tinted. Cleaners that contain ammonia, alcohol, or detergents are not the best as they mostly leave streaks or smudges. A good cleaner should also not temper with the window tint film.

Things to avoid during the procedure

There are several things to avoid when cleaning car windows:

  1. Do not allow the cleaning clothes to touch the dash to avoid picking up contaminants
  2. Do not use alcohol to clean the windshield wipers, using alcohol for wiper treatment may dry the rubber out
  3. Make sure the wax is dry before wiping it off the windshield, wet wax can leave a smudge
  4. Just like car washing, whenever you are cleaning your vehicles windshield stay out of direct sunlight to avoid premature drying
  5. Do not allow the glass cleaner to dry on the windshield
  6. Do not use dirty clothes to clean windows, change them often
  7. Do not use steel wool or sharp edges to clean the glass to avoid scratching the glass

Test drive your car at night to observe your clean windshield. Many drivers will be amazed at how clean the glass is and the reduced glare from oncoming traffic. Drivers will appreciate your auto detailing efforts with clean glass.


Usually, one should apply the cleaner onto the window directly, not on the towel. The towel should be used to spread the cleaner on the glass. Also, it is highly recommended that you start from the edges towards the center.

Up-and-down or sideways motions should be used while using the cloth to wipe during cleaning. Be careful with tint film as it can come off with some products.

cvv1Cleaning car windows in the sun is a bit hard. One should, therefore, find a bright spot to clean the glass windows. Some streaks may not even be visible in sunlight. So, you should choose a shade to make your environment comfortable.

Don’t forget to clean the windshield washers to keep your front windshield glass surface as clean as possible. You can apply the same method to clean the rear window as well.

My wife teases for always trying to keep my windshield streak free. I really liked this post though because I like keeping my car looking nice. I hadn’t realized that vinegar based cleaners are safe to the environment, which is definitely important to me. Thanks for sharing this post!

I have never used vinegar to clean my car’s windows before, but it is good to know that it would be tolerant with the tints. However, I have used a mixture of water, vinegar and rubbing alcohol on the windows on my house before. Do you know whether or not it would be a good idea to use rubbing alcohol on a car’s, though?
