4 Best Ways to Clean Car Windows

The crucial question after thoroughly washing your vehicle is how to clean car windows. It’s up to you to find the best way to do that job. Clean windows enhance visibility and give your car the final shine and classy look.

However, many drivers have a problem with ugly streaks remaining on the glass in the end. The secret is in the window cleaner and the technique of washing both inside and outside windows. Let’s find the best way to transform your car into a crystal clean beauty.

Washing the Outside and Inside Car Windows

Even though most drivers believe that the steps of cleaning car windows inside and outside are similar, the truth is that you should use specific strategies for them. The reasons are different problems these two sides include.

Outside windows

When you decide to wash outside windows, you will deal with excessive dirt and water spots. That side is exposed to different weather conditions to which they respond differently depending on the window making, varieties of glass, age of the car, and regularity of washing.

Inside windows

When it is about inside windows, you should consider the type of window tint film and possible accumulation of rubber, vinyl, and even plastics on the glass surface. Also, heat and UV lighting will affect this side of the window differently.

The Procedure for Washing the Car Windows

The Procedure For Washing The Car Windows

Always wash your vehicle from dirt and bugs before you begin cleaning the windows. Regardless of whether you decide to wash the car by yourself or in a car wash, it will make cleaning windows much more comfortable.

However, if you decide to wash your car by your hands, try to do it when the temperatures are not too high or find a shadow to prevent the cleaner from drying before you wipe it off.

Cleaning the outside windows

Start with the spraying glass cleaner over the windows to dissolve dirt and stuck-on bugs. Take care to be fast to prevent drying of the window cleaner.

Then, use soft and clean microfiber cloths for windows to finish the job. Pick out the lint-free one and change them to avoid smearing residue of soap, dirt, and wax over the glass.

The trick to getting the crystal clean windows is in motions. Always wipe them vertically first and follow with the horizontal movements to make an ideal pattern. Side-to-side motions will give the window the final shine without any streaks on the surface.

Cleaning the inside windows

When you need to clean the inside glass, you should be more careful. Never spray the window cleaner directly on the glass but moisten the microfiber cloth and wipe the windows with it. Use the same pattern and clean the inside windows in both directions.

That way, you will avoid wasting the cleaner, and additional washing the interior parts of the vehicle since at least half of the solution will spray on them. Plus, if you use the manufactured glass cleaner, the chemicals may damage the inside plastic parts.

The Best Automotive Cleaners

Although you can find a bunch of chemical window cleaners at your local shop, using natural ones is always a better solution. Therefore, I will give you a list of the best DIY options you have at your disposal.

1. White vinegar and dish detergent

White vinegar and dish detergent

What you need

  • 1/4 cup white vinegar
  • 2 cups of water
  • 1/2 tsp dish detergent


Take a bucket and mix white vinegar with water and dish detergent in it. Basically, it will only take a few minutes to get a great window cleaner for your car.

2. Rubbing alcohol and white vinegar

What you need

  • 50% of rubbing alcohol
  • 50% of distilled water
  • A cupful of white vinegar


Mix all the ingredients in a spray bottle. Spraying this agent directly onto the window is always a better option than applying it with a cloth.

3. Rubbing alcohol and window cleaner

What you need

  • 15% of rubbing alcohol
  • 70% of water
  • 15% of window cleaner


Some drivers prefer mixing window cleaner with rubbing alcohol. It is actually an excellent solution. However, keep in mind that you may need to rinse the windows at the end, depending on the type of cleaner you use.

4. Cleaning agents

Cleaning agents

There are a wide variety of chemicals for cleaning car windows available on the market. These agents are a fast and comfortable way to clean them without streaks left on the glass.

You will need

  • Automotive glass cleaner
  • Distilled water if you pick out the cleaner you need to dilute


In most cases, you can purchase the ready-for-use cleaner. The only thing you should do is to add it on the microfiber cloth and start cleaning according to the established pattern.

If you choose the one you need to dilute, mix it with water in a bucket, and then apply the solution on the window with a soft microfiber cloth.


Whatever cleaning solutions you decide to choose, take care to avoid ammonia-based ones. Ammonia may damage leather vinyl, plus you will need hours to ventilate the interior of the vehicle.

Special Notes

Windshield and rear window

These windows are hardest for cleaning because of their size and the angle at which they are embedded.

Therefore, you should spray the chosen mixture over them and clean thoroughly with a sponge. Wipe the surfaces with a soft and clean microfiber cloth to finish the process successfully.

Hard water spots

Since the water in the US is usually hard and contains calcium, magnesium, and lime, you will often notice hard water buildup on the windows of your car.

Try to clean these stains with white vinegar or alcohol as soon as possible. Then dry the glass with the soft cloth until removing all the residues.

Cleaning bug spatter

I hate stubborn bugs splattering on the windows of my car. If you have the same problem, you should purchase a product specially formulated for that purpose.

If you prefer environment-friendly options, you can try to remove these remains by sprinkling the solution of baking soda. Let it sit there for a few minutes and clean the glass with the microfiber cloth.
