How can improper cleaning techniques affect glass surfaces?

1. They can enhance the clarity of the glass

2. They may lead to scratches and other damage

3. They are generally harmless to the surface

4. They improve the longevity of the glass

The correct answer is: They may lead to scratches and other damage

Improper cleaning techniques can significantly impact glass surfaces, primarily leading to scratches and other forms of damage. When abrasive materials or harsh chemicals are used, they can create fine scratches on the surface of the glass, reducing its clarity and aesthetic appeal. For example, using scouring pads or gritty cleaners against the glass can permanently mar the surface, making it more prone to dirt accumulation and further damage over time. This kind of surface damage can also weaken the glass, making it more susceptible to breakage. Additionally, improperly cleaning glass may leave behind residues that can attract dirt and grime, further complicating the maintenance of the glass. These residues can also potentially lead to fogging or clouding, which obstructs visibility. Therefore, proper cleaning techniques are essential not only for maintaining the appearance of the glass but also for ensuring its durability and structural integrity over time.
