Red Seal Glazier Practice Exam

What is an inappropriate material to use for cleaning glass?

1. Paper towels

2. Microfiber cloths

3. Scrub brushes

4. Non-abrasive sponges

The correct answer is: Scrub brushes

Using scrub brushes for cleaning glass is considered inappropriate because they can be abrasive and may scratch the surface of the glass. Glass surfaces require gentler cleaning materials to maintain their clarity and finish. While scrub brushes are effective on tougher surfaces, their bristles can create micro-scratches on glass, which not only detract from the appearance but can also make the glass more prone to collecting dirt and grime over time. In contrast, materials like paper towels, microfiber cloths, and non-abrasive sponges are designed for safe glass cleaning. Microfiber cloths, in particular, are known for their ability to lift dirt and grime without scratching, making them an excellent choice for maintaining the integrity of glass surfaces. Non-abrasive sponges also provide a soft surface that won't harm the glass. Paper towels can sometimes leave lint, but they are still generally considered safe. Understanding the appropriate cleaning materials will help ensure that glass surfaces remain clear and undamaged.
