Glass coating is a technology that forms a protective film on the glass surface. It not only provides an extra protective layer but also forms a hydrophobic layer, making it difficult for water droplets and dust to adhere to the glass, thus maintaining visual clarity. So, how often should glass coating be applied?

 

Generally, the effect of glass coating lasts for 1 to 2 months. However, the specific duration can vary depending on the coating material and brand. Therefore, in actual use, it is recommended to clean and maintain the coating promptly when the water-repellent effect weakens or an oil film appears on the surface to maintain optimal performance.

 

When the water-repellent effect of the glass coating begins to weaken, water droplets may become trapped and difficult to flow. At this point, maintenance should be considered. In addition, the glass coating also needs timely cleaning and maintenance when faced with oil film contamination to ensure it continues to perform at its best.

 

To maintain glass coating, choose professional glass cleaning agents and tools. Avoid using cleaning agents containing acidic or alkaline ingredients to prevent damage to the coating. Regular cleaning, wiping, and maintenance of the glass are also essential.
