Question

To clean polymer surface of indoor Menu Board, use a dry towel to wipe front surface firmly. A) True

B) False

Answer 1

Using a dry towel to clean a polymer surface of an indoor Menu Board is not recommended as it can cause scratching; a wet cloth should be used gently instead.

Step-by-step explanation:

The correct answer to whether one should use a dry towel to firmly wipe the front surface of a polymer indoor Menu Board is B) False. Instead, for cleaning sensitive surfaces such as polymer or optical components, a more gentle and potentially moist method is recommended. This is because using a dry towel might not effectively remove all debris and may even cause scratching by dragging embedded particles across the surface. For delicate surfaces, typically, a wet cloth is preferred, and it should be drawn once across the object then discarded or thoroughly cleaned before reuse to prevent surface damage from accumulated debris.
