What is the recommended cleaning method for non-porous hard surfaces greater than 100 sq ft?

1. Vacuum with a standard vacuum cleaner

2. Damp-wipe surfaces with detergent

3. Steam clean with high heat

4. Soak in bleach solution

The correct answer is: Damp-wipe surfaces with detergent

Damp-wiping surfaces with detergent is the recommended cleaning method for non-porous hard surfaces greater than 100 square feet. This approach is effective in removing mold spores and any potential contaminants without introducing excessive moisture, which could promote further mold growth. Using a detergent solution helps to break down dirt, oils, and biological deposits, facilitating their removal from the surface. In contrast, vacuuming with a standard vacuum cleaner may not effectively capture all mold spores or contaminants, especially if the vacuum is not equipped with a HEPA filter. Steam cleaning with high heat can be useful for certain applications but may not be appropriate for all surfaces and could potentially damage some materials. Soaking surfaces in a bleach solution is not advisable for large areas, as excessive moisture can lead to mold resurgence, and the effectiveness of bleach on porous surfaces is limited. Thus, damp wiping with detergent balances thorough cleaning while minimizing the risks associated with moisture and surface damage.
