Q: How do I maintain clean business windows?

• <div><p>Regular cleaning, non-abrasive cleaners, and scheduling professional services every few months help maintain clarity and shine.</p></div>

Q: Why am I getting mold on my windows?

• <div><p>Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.</p></div>

Q: Can hard water stains on glass be permanent?

• <div><p>Hard water stains can permanently damage your glass if left untreated. The minerals dissolved in the water can etch the glass, causing long-term damage and affecting the overall integrity of the surface. Luckily, it is pretty simple to remove hard water stains by using vinegar, baking soda, or commercial cleaners.</p></div>

Q: What can I use to clean windows without streaking?

• <div><p>One of the best professional cleaning solutions that won&rsquo;t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.</p></div>

Q: Do you have to take window screens down to clean them?

• <div><p>No, but removing window screens will achieve a deeper clean. If you aren&rsquo;t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.</p></div>
