Apart from this, it is important that you look out for streaks when cleaning your car from the inside for the sake of visibility and, ultimately, your safety.

Put Together Your Supplies

First, you need to assemble the necessary instruments for cleaning your windows. Having all the necessary equipment in one place helps ensure that you’re organized with your cleaning. Surely, running around for a piece of equipment while you’re cleaning your windows is the last thing you’ll want to do.

The cleaning tools you’ll need are simple, basic tools that you can easily get in a local store close to you or on an online store like Amazon. These tools are inexpensive; therefore, with a little change, you’ll have the best tools to clean your windows. Here are the tools you’ll need:

Microfiber Cloth

Why do we recommend microfiber cloth? Microfiber is a soft, smooth material that is not only hand-friendly but also possesses outstanding properties to remove any dirt or debris on your windows. This cloth easily absorbs the glass cleaner, making it a more efficient material for cleaning.

Furthermore, it is better than many other alternatives like newspapers and paper towels. The newspaper will not only make your cleaning difficult but will leave ink residue lying all over your car windows and your hands. Paper towels, on the other hand, shred easily, meaning you’ll have to use a lot of them to get the best out of your cleaning.


Of course, you’ll need water. However, you must ensure you add the right quantity of water. Too much water will render your cleaning ineffective, and too little will litter your windows with streaks. In the next step, where we talk about preparing the best cleaning solution, you’ll get to know the right quantity of water to use.

Glass Cleaner

When looking for a good, clean windshield tool, you should be very careful. There are many cleaners out there you should avoid. Most especially, steer clear from ammonia-based cleaners as they would prove very damaging to your tint, leather, and vinyl.

If you would use a glass cleaner, you should go for the best car windshield cleaning tool. Also, it matters how you apply the cleaner and the quantity you apply. A little negligence in properly measuring the quantity of cleaner you use could widely deter your chances of having a clean window without streaks.


Cleaning inside car windows using vinegar is one of the most efficient ways of cleaning your windows. Vinegar possesses powerful chemicals that make a difference on your windows. However, it would be best if you were careful of the quantity of vinegar you use; too much could damage your windows.

Rubbing Alcohol

One more piece of equipment you should get is alcohol. A window cleansed with a bit of alcohol appears clearer than one cleaned without alcohol.

Prepare The Cleaning Solution

The next step is to mix your supplies. It would be best if you did this before getting into your car to avoid spillage on your seats and plastic rears. When you’re ready to mix your cleaning solution, you should use either of the two methods.

First, you use only alcohol, water, and vinegar. When preparing your solution using this method, you should be conscious of the quantity of each piece of equipment you use. Your mixture should contain 50% water, 50% alcohol, and a capful of vinegar.

Second, you use only water, alcohol, and glass cleaner. This method requires that you have a higher concentration of water compared to the other method. Your solution should contain 70% water, 15% alcohol, and 15% glass cleaner.

Either of the methods you choose to use, ensure your mixtures are prepared in a clean bowl, bucket, or spray bottle. Also, you could choose to use only your glass cleaner if you’re opting for a less thorough cleaning. However, you should do a thorough cleaning from time to time.

Hop Into A Comfortable Space in Your Car

This step may seem less important, but it may prove to be the difference between a good cleaning and an excellent one. When getting into your car, you should sit in a space where it will be easier for you to clean all the windows. Cleaning will be difficult if you sit in the driver’s seat, so you should utilize the back seat or passenger’s seat (for the windshield.)

Wipe The Glass Clean

First, use a clean, dry microfiber cloth to wipe the glass completely clean. This will help remove little dust that could soil your cleaning solution.

Degrease the Windows and Windshield

Next, pick up a different cloth, add a tiny bit of alcohol, and rub off your glass. This will help rid any grease on your glass. You can also use vinegar for this step – it will have the same effect.

Clean Thoroughly

Next, please pick up a different cloth and soak it in your solution. If you have your mixture in a spray bottle, spray it on the cloth, not on the windows or windshield. Spraying your cleaner directly on your glass is not advisable by an expert because you may, in the process, spray the cleaner on your seats and plastic rears which could damage them.

After your cloth is soaked with the cleaner, clean your glass in an up-down and side-to-side motion. Using this technique, rather than cleaning in a circular motion, will help you clean interior windshield haze and keep your windows without streaks. It is a simple hack to clean inside the windshield, and you should utilize it.

If you want to take it to a better level, you could use a cleaner tailor-made for cleaning inside windshields. It’s what many experts call the best windshield cleaner for inside cars, and you can find it here.

Other Alternatives

You can also go on the route of cleaning car windows with Windex. While some experts will suggest you do not use Windex on tinted windows, there’s no proof that cleaning inside the windshield with Windex is harmful. However, if you had your windows tinted by someone else, you may want to skip using Windex. You can watch this for more information.
