When dealing with hard surface porous flooring, what initial step is recommended for mold removal?

1. Using a wood floor cleaner

2. Steam cleaning the surface

3. Wet vacuuming the area

4. Damp wiping with a vinegar solution

The correct answer is: Wet vacuuming the area

When addressing mold removal on hard surface porous flooring, wet vacuuming the area is a critical initial step. This method is effective because it allows for the extraction of both mold spores and any moisture present in the porous material. By using a wet vacuum, the mold contamination can be contained and removed without further dispersing spores into the air, which is a risk when using other methods. Additionally, wet vacuuming helps to minimize the potential for cross-contamination to other areas of the building. This method is especially important in the early stages of mold mitigation, as it prepares the surface for further cleaning and remediation processes. While other methods, such as damp wiping with a vinegar solution or steam cleaning, can also be effective, they are typically secondary steps in the process, following the extraction of visible mold and moisture. Ensuring that the area is first vacuumed prevents complications that could arise from disturbing settled spores or spreading mold to uncontaminated surfaces.
