atermarks or waterspots on windows can be pesky, tarnishing the clarity and beauty of our view. Understanding how watermarks form and adopting preventive measures can help keep your windows spotless and ensure they remain a portal to the outside world.

The simplest way to prevent these is through (shocker!) regular window cleaning.

Watermarks on windows are a result of mineral deposits left behind when water evaporates. When rainwater or water droplets from sprinklers or hoses come into contact with a glass surface, they carry dissolved minerals such as calcium, magnesium, and silica. As the water dries up, the minerals are left behind, forming stubborn spots and streaks known as watermarks or waterspots. How irritating!

The simplest way to prevent these is through (shocker!) regular window cleaning. By wiping away water droplets before they have a chance to evaporate, you can prevent mineral deposits from forming. Use a squeegee or a microfiber cloth to ensure a streak-free finish. Using the right cleaning solution can make a significant difference. For the DIYers out there, avoid products containing ammonia, as they can leave streaks on the glass. Opt for vinegar-based or eco-friendly window cleaners that effectively dissolve mineral deposits without leaving residue behind.

Cleaning windows on hot, sunny days can worsen watermark formation. The heat can cause water to evaporate quickly, leaving behind more concentrated mineral deposits. Consider cleaning windows in the early morning or late afternoon when temperatures are lower and the sun is less intense. Using distilled or filtered water for window cleaning can also minimize the presence of minerals that cause watermarks. This method is especially helpful for areas with hard water, where mineral deposits are prevalent.

Strategically placing awnings or overhangs above your windows can provide some protection from direct rainwater exposure. This reduces the amount of water reaching the glass surface and consequently lowers the likelihood of watermarks.
