7 effective ways to save the window from fogging

A prevalent problem that many homeowners deal with is window fogging, particularly in the winter months. Not only can persistent fogging be a minor annoyance, but it can also cause mold growth, damage to window frames, and an uncomfortably cold living environment. It’s possible to avoid frosted windows and save time, money, and aggravation.

The temperature and humidity differential between your home’s interior and exterior is the main reason why windows fog up. Condensation occurs when warm, humid air contacts the window’s cooler exterior. Although this is a normal process, it can be managed with a few useful techniques.

We’ll look at seven doable strategies in this post to maintain clear, fog-free windows. These fixes can be as easy as making small daily changes or as complex as remodeling your home. You can have cleaner windows and a healthier interior environment all year long if you put these suggestions into practice.

The following methods will assist you in effectively addressing fogged-up windows in your living room, bedroom, or even your automobile. Now let’s explore the best ways to keep your house dry and comfortable while preventing window fogging.

Shaving foam

If the shaving foam is not suitable for my skin type, I will not use it. This tool is useful for clearing fog from windows, so don’t discard it. Apply the foam ball to the glass in a consistent layer by squeezing it onto the sponge.

After 30 seconds, use a cloth to gently wipe off the extra fruit in circular motions, much like you would when polishing. For roughly a week, the visible result is sufficient; after that, the process must be repeated.

It can be difficult to prevent windows from fogging up, especially in the winter. In order to maintain good visibility and a comfortable interior atmosphere, this article examines seven useful and efficient techniques for preventing window fogging. These easily applied techniques, which range from using dehumidifiers and raising ventilation to applying anti-fogging treatments and caulking window leaks, can drastically reduce condensation on your windows. These pointers will assist you in keeping your view clear all year long, whether you’re dealing with windows in your house, car, or place of business.

Alcohol and glycerin

When combined with alcohol, pure glycerin creates a fat, water-repellent layer on the glass that effectively prevents fogging. Combine 10 milliliters of glycerin with 100 milliliters of alcohol, and then apply the mixture to recently cleaned glass. The last step is to wipe with a clean cloth.

Glycerin is made less sticky by adding alcohol to it. Extreme circumstances can also call for vodka. It vanishes when alcohol is applied, leaving behind a thin, imperceptible film that repels water on the glass.


Before, people would clean the glass with ammonia and a rag before wiping it with a newspaper in areas without window washing facilities. For many years, it was the most efficient technique.

Divorces could be avoided, the window could remain cleaner longer, and it could be shielded from foggy conditions thanks to this polishing. This method is still applicable today since newspaper absorbs moisture well, which causes dust to accumulate on the glass.


Aids in eliminating water stains on glass and salt solutions. Fill a glass with 100 milliliters of water to prepare it. Add 35 grams of table salt there and stir until all of the salt is dissolved. After that, dilute the concentrate with two liters of water.

After that, wipe the window with a cloth dipped in the solution. You must add one liter of water and process the glass once more if the white stripes are still visible after it has dried.


Excessive indoor heat and moisture is the primary cause of condensate’s appearance. Venting will facilitate its removal.

When someone is nearly always home, you can simply occasionally prop open a window wide.

It is better to leave the window open for micro if the room is continuously damp, say from the drying underwear, and you are gone from the office for an extended period of time. The recognizable ajar window will be entirely replaced by this feature.

It is also possible to mount the ventilation valve, and you can do this even a few years after the windows are installed. It is inserted into the wall beneath the windowsill or into the window profile. The valve can guarantee that the house is properly ventilated and is reasonably priced.

Creating a profile right away with integrated self-evidence is another method to live with clear, unfogged windows. In this instance, holes in the top and bottom of the frame will guarantee proper air circulation.


This vegetable will assist in preventing fogging as well. Use any specialized tool to clean the window, then wipe it dry.

After that, carefully process the glass throughout the area while cutting raw potatoes in half. Because of the formation of a thin starchy film on the surface, the glass will not fog.

Effective Way Description
Use a Dehumidifier A dehumidifier reduces moisture in the air, preventing fog on windows.
Install Weather Stripping Sealing gaps with weather stripping keeps cold air out and reduces condensation.
Ventilate Properly Ensure proper ventilation in your home to allow humid air to escape.
Use Anti-Fog Spray Apply anti-fog spray to windows to create a clear, fog-free surface.
Insulate Windows Double-glazing or insulating film can keep windows warmer and reduce fogging.
Keep Indoor Plants in Check Too many plants can increase indoor humidity; manage their number to avoid excess moisture.

Maintaining clear and comfortable windows can greatly enhance your home’s visibility and comfort. You can maintain your indoor air quality and your windows clear by using these seven practical techniques. All these methods are easy to use and have a significant impact, particularly in the winter.

It is essential to have adequate ventilation. Reducing humidity levels, which are frequently the primary cause of window fogging, can be accomplished by making sure that fresh air flows through your house. To maintain a balanced indoor climate, open windows on occasion and use exhaust fans in areas like the kitchen and bathroom.

A dehumidifier can be a very useful tool as well. By removing extra moisture from the air, these gadgets reduce humidity and stop condensation on your windows. It’s a workable answer, particularly in regions with high humidity levels naturally.

Maintaining a constant temperature in your house is another helpful suggestion. Condensation can be prevented by using a programmable thermostat to keep indoor temperatures constant. Sudden changes in temperature can cause condensation.

Applying anti-fog coatings or sprays to your windows can act as a temporary moisture barrier for a more hands-on approach. These products can provide immediate relief from persistent fogging and are simple to use.

Installing storm or double-glazed windows can also produce an insulating barrier that lessens the temperature differential between the window’s exterior and interior surfaces. This reduces fogging and raises energy efficiency levels all around.

Lastly, remember to take care of any sources of excessive moisture in your house. To create a drier, fog-free atmosphere, seal leaks, air dry clothing outside, and cover pots while cooking. You can have clear windows and a cozier living area by combining these tactics.
