Can You Use Comet on Glass?

No, you should not use Comet on glass.

The "Glass Care & Cleaning Instructions" explicitly advise against using abrasive cleaners like Comet on glass surfaces. Following these precautions is essential for maintaining the clarity and integrity of your glass.

Why Comet Should Be Avoided on Glass

Comet is classified as an abrasive cleaner, meaning it contains fine, gritty particles designed to scour tough stains. While effective on some surfaces, these abrasive properties make it unsuitable for glass. The reference specifically states, "Precautions: Avoid abrasive cleaners such as Ajax, Comet, and anything containing Cerium Oxide."

Using abrasive cleaners on glass can lead to several undesirable outcomes:

• Scratches: The abrasive particles in Comet can easily scratch the smooth, delicate surface of glass. These micro-scratches accumulate over time, making the glass appear dull and cloudy.
• Dulling: Repeated use of abrasive cleaners erodes the glass's polished finish, leading to a loss of its natural shine and transparency.
• Reduced Clarity: Scratches and surface damage impair the light transmission through the glass, diminishing its visual quality and making it harder to see through.

Recommended Practices for Glass Cleaning

To ensure your glass remains pristine, it's crucial to follow care instructions carefully. The primary directive from the provided reference is to avoid any product identified as abrasive.

Here's a summary of the cleaning agent recommendations based on the reference:

While the reference suggests that "A clean rinse should follow the use of these products" (referring to generally acceptable cleaners not explicitly listed as problematic), the core message for long-term glass care is to steer clear of harsh, abrasive compounds. Always adhere to the manufacturer's printed instructions for any cleaning products you do use on glass.
