Clean car window from the inside: properly clean fogged or dirty windshields.

One of the first things you need to do before your daily commute is to make sure your windows are properly cleaned and have no residue left on them. In the winter, it’s more important than ever to keep your windows clean. Dirt not only makes it easier for fog to form on your window, but it also gives the fog a dirty color, making it harder to see through the fogged window. If you’re having trouble seeing the road clearly on your commutes, learn how to clean your car window from the inside in this article.

How to clean the car window from the inside?

Cleaning the car window from the inside - simple tips

The inside of a car’s windshield deserves a good cleaning just as much as the outside, especially if your car windows fog up regularly. Fortunately, you can get a good cleaning pretty easily in just a few steps.

  • Wipe the car windows dry: Wipe the inside of the car windows with a dry microfiber cloth, working from top to bottom in an up-and-down motion. This prep step removes the nearly invisible film layer of dirt and dust particles that come from plastic, vinyl and rubber in the car.
  • Add cleaner: Spray the cleaning solution directly onto another microfiber cloth. Just a few squirts at a time should be enough. Do not spray the cleaner directly onto the glass. Too much cleaner can cloud the glass.
  • Apply cleaner: rub the microfiber cloth moistened with the cleaner over the glass in a circular motion, again working from top to bottom.
  • Where a gripping tool is useful: the bottom corners of the windshield can be tricky and nearly impossible to reach, so a gripping tool can prevent some awkward contortions on your part.
  • Dry the glass: wipe the glass with the other side of your dry or fresh microfiber cloth for a streak-free finish. Repeat steps 2 through 4 until it shines.

Cleaning the car window from the inside - tips against fogging in winter

When you drive in the winter, you may find that your windows fog up, making it extremely difficult to see the road. How do you prevent car windows from fogging up in the winter? The following methods range from free techniques to some inexpensive products.

Apply anti-fog spray for better visibility.

Use an anti-fog spray for fogged car windows

Anti-fog spray contains chemicals that prevent water from condensing on the glass. Remember that fog forms on the inside of your windshield in the winter, so make sure you get a spray designed for interior glass.

Thoroughly cleaning your car windows before applying anti-fog spray is key to its effectiveness, so don’t neglect it.

Don’t use a recirculating air feature in the winter

Keep the air circulation in the car off


If your windows are fogging up more than usual, check the recirculation button on your ventilation system. When you circulate the air, moisture collects and begins to condense on your interior glass.

Instead, set your fan to let in fresh air. Especially in the winter, this fresh air is cold and therefore especially dry. This helps keep your car windows clean.

Switch on heating and air conditioning at the same time

Turn on the heating and air conditioning in the car at the same time against fogging

When it’s cold outside, you want the heater in your car to keep you warm. But warm air causes condensation to form on the windshield. So how can you stay warm without fogging up the glass?

Turn on the air conditioner at the same time you turn up the heat in your car. The air conditioning dries the air. By reducing the moisture in the warm air blowing into your car, you reduce the likelihood of your windshield and windows fogging up.

Just make sure the A/C knob is on when you turn up the heat.

Buy a Silica Dehumidifier

Silica dehumidifier helps to prevent the fogging on the car window


Silica dehumidifiers work just like silica packets in clothing. When you buy new clothing, there are often silica packets in shoes and clothing boxes to remove moisture and water from clothing. For clothing retailers, this prevents mold growth in the clothing box that can result from trapped moisture. Silica dehumidifiers can do the same for your car.

Use home remedies for fogging to clean the inside of your car window.

Use home remedies to clean car windows from the inside in winter and prevent misting up

If you don’t want to use the commercial anti-fog sprays, there are some home remedies you can use to prevent the fog from forming:

  • Shaving cream: spray some on a towel and wipe it over the glass surface. Then wipe the car window with a clean cloth.
  • Potato: Oddly enough, the starch and sugar in a potato can act as an anti-fog agent. Simply cut a potato in half and rub the cut side on the windshields. Wipe off the excess potato juice so it doesn’t leave a white starch coating on the glass.
  • Cat Litter: Similar to silica, cat litter absorbs moisture and keeps it locked in. A DIY trick to reduce window fogging in the winter is to buy clean, dry cat litter. Fill an old sock up to the ankle area with it and then tie the sock shut. Place these cat litter filled socks on your dashboard when the car is parked to prevent window fogging.
