Q: How often should I clean my windows?

• <div><p>Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.</p></div>

Q: What removes glass labels?

• <div><p>You can use hot, soapy water, white vinegar, rubbing alcohol, window cleaner, nail polish remover, WD-40, and cooking oil to remove glass labels. You can also apply heat with a hair dryer or steam cleaner. Use a plastic scraper or credit card to remove the adhesive, as a razor blade can permanently scratch your glass.</p></div>

Q: Is a house supposed to be clean when you buy it?

• <div><p>Unless it&rsquo;s written into the purchase agreement, there&rsquo;s no legal obligation that a house you&rsquo;ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn&rsquo;t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.</p></div>

Q: Are windows included in a deep clean?

• <div><p>Window cleaning depends on how the cleaning service defines their deep cleaning tasks, so pay attention to the details. You certainly should make sure window cleaning is included in the package. Some services will include it as an add-on, so you may have to pay extra. Find out if the cleaning includes interior windows only, or interior and exterior windows. Exterior windows may cost more. </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>
