Hard Water Stain Removal and Protection Service
“Hard water stains on your windows can be unsightly and difficult to remove, but we have the solution. Our expert team will effectively eliminate those stubborn stains and restore your glass to its original clarity.
Once the stains are gone, we’ll apply a hydrophobic coating that acts as a protective barrier, repelling water and preventing future build-up. This coating not only keeps your windows looking pristine for longer, but it also reduces the need for frequent cleaning. With this added protection, your windows will stay clearer, more resistant to water spots, and easier to maintain, saving you time and effort in the long run.”
Hard water stains are caused by mineral deposits left behind after water evaporates from a surface, particularly calcium and magnesium, which are common in hard water. Here’s the science behind it:
- Hard Water Composition: Hard water contains dissolved minerals like calcium (Ca²⁺) and magnesium (Mg²⁺). These minerals are picked up as water flows through underground rock formations, such as limestone or chalk, which contain high levels of these minerals.
- Evaporation Process: When hard water comes into contact with a surface, such as a window, and evaporates (often due to heat or sunlight), the minerals in the water are left behind. These minerals form deposits, which gradually accumulate and leave behind the unsightly spots or streaks.
- Formation of Stains: Over time, as the water repeatedly evaporates from the surface, these mineral deposits build up, forming hard water stains or “water spots.” The stains can range from light, cloudy marks to stubborn, thick deposits depending on the mineral content in the water and the frequency of exposure.
- Chemical Reaction: Calcium and magnesium, when exposed to air or sunlight, can react with carbon dioxide (CO₂) in the atmosphere, forming calcium carbonate (CaCO₃) and magnesium carbonate (MgCO₃). These compounds are insoluble in water, which means they stay stuck to the glass surface, leading to the formation of hard water stains.
- Persistent Build-Up: If left untreated, the build-up can become more challenging to remove, as it hardens over time, especially when combined with soap scum or environmental pollutants. This is why hard water stains can become etched into the surface of the glass, making it harder to restore to its original clarity.
By applying a hydrophobic coating after cleaning, you create a water-repellent surface that prevents these minerals from adhering in the first place, making it easier to keep your windows clean and spot-free in the future.
