5 Types of Stains That Can Damage Your Windows Appearance

5 types of stains that can damage your windows appearance

Windows are an important part of any home or commercial building. They allow natural light to shine through and can add a touch of elegance to any room. However, if you neglect them, they can become dirty and stained over time, leaving behind unsightly marks that detract from your property's appearance.

If you want your windows to stay in peak condition, regular window cleaning is essential, but how do you spot the signs of a dirty window? Here are six common stains that may indicate your windows need attention.

Mold and Mildew

Mold and mildew are two common types of fungi that thrive in moist environments. They are often found on the surface of windows, particularly around the edges, where they get less airflow and can cause health problems for those who are allergic or asthmatic. If you see signs of mildew on your windows, consider calling a professional interior window washing crew right away! Doing so will ensure the safety of your home and protect the health of you, your guests, and your loved ones.

Wrong Cleaning Products

Many people think that any old dishrag and soapy substance will do when it comes to maintaining their windows. Unfortunately, this just isn't true. If you use the wrong products to clean your windows, they may leave streaks behind or promote further issues for your property when it rains.

In order to get better results during your cleaning project, you should use a window cleaner specifically formulated for your windows. This will ensure that the water is able to be absorbed into the glass without leaving additional residue behind.


Insects like to hang out on windows because they get lots of sunshine, but also because insects love things with lots of sugar in them (like plants). When they die on a window, their bodies decompose into a blackish-brown color that can decrease your curb appeal and make for a less-than-appealing view. To get rid of these bodies, you can use a window cleaner that has insecticidal properties or deter these pests before they're able to do any damage.

Bird droppings

If a bird decides to poop on your window, it will leave stains that are difficult, if not impossible, to deal with. These stains can also damage your window as they dry in, so it's important to get them cleaned off as soon as possible.


Dirty windows can make your windows look unkempt and filthy and are one of the most common signs that your windows are in need of professional cleaning.

The more dirt your windows accumulate, the less light they allow into your home or office. This makes it harder for you to see and might lead to higher energy bills from turning on lights more often than necessary.

Get Professional Help

To ensure your windows are always tidy, it's a good idea to wash them professionally at least once per year. This will help prevent dirt and grime from building up on the glass, which can save you money and keep your home looking nicer overall.

If your situation requires more frequent window cleaning, however, you should consider hiring a professional window cleaning company. They will know exactly what solutions and products to use and give your windows a spotless scrub down that sticks.
