Red Seal Glazier Practice Exam

What type of surfaces can non-abrasive cleaners be safely used on?

1. Only non-painted surfaces

2. Only outdoor glass surfaces

3. Coated and uncoated glass surfaces

4. Wood and metal surfaces

The correct answer is: Coated and uncoated glass surfaces

Non-abrasive cleaners are designed to clean surfaces without scratching or damaging them. The use of such cleaners on coated and uncoated glass surfaces is particularly advantageous, as glass can be sensitive to harsh chemicals and abrasive materials which may lead to damage or clouding. Uncoated glass surfaces benefit from non-abrasive cleaners as they help maintain clarity and shine without risking scratches. Coated glass, on the other hand, often has a protective layer that can be removed or damaged by stronger cleaned or abrasive substances. Non-abrasive cleaners are gentler and help preserve both types of surfaces, making them suitable for maintaining the integrity and appearance of glass products. The other options are limited to specific surface types that do not encompass the versatility and safety non-abrasive cleaners offer for both coated and uncoated glass. Non-abrasive cleaners may not be appropriate for all situations regarding other materials such as wood and metal, given their unique cleaning requirements.
