Q: What is the best DIY cleaner for hard water stains?

• <div><p>It depends on the surface you&rsquo;re trying to clean. For example, a mixture of vinegar and water is a good option for a deep cleaning, including removing hard water stains from glass or stainless steel. However, vinegar is too acidic for granite and other types of natural stone, so it&rsquo;s better to use a combination of baking soda and water on those surfaces. </p></div>

Q: What is the difference between window washing and window cleaning?

• <div><p>Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home&rsquo;s energy efficiency.</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: Do glass block windows need maintenance?

• <div><p>Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.</p></div>

Q: How do you clean well water off windows?

• <div><p>Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.</p></div>
