Which of the following commercial cleaners should not be used daily on the PCS2?

The choice of Pro-tech as the cleaner that should not be used daily on the PCS2 is based on the specific formulation and intended uses of commercial cleaners. Pro-tech may contain components that are too harsh for daily application on certain surfaces of the PCS2. Over time, these harsher chemicals can degrade materials or interfere with the functionality of the equipment.

In contrast, Windex is typically formulated for glass and can be safe for daily usage on specific surfaces, while soap and water are gentle cleaning agents that can be used regularly without risk of damage. Regularity and compatibility with the materials the PCS2 is made from are critical considerations in choosing a cleaner for daily use, further solidifying why Pro-tech, despite being an effective cleaner, should be reserved for less frequent application to maintain the integrity of the PCS2.
