For non-porous items that are classified under condition 3, the most effective cleaning method is HEPA vacuuming followed by damp wiping. Condition 3 refers to environments where there has been significant contamination from biological materials, such as sewage or other hazardous microbes.

HEPA vacuuming is essential because it effectively captures very small particles and potentially harmful biological contaminants. This step helps to safely remove a large volume of contamination without dispersing it into the air. Following this, damp wiping is critical as it ensures that any residual contamination is removed from surfaces, while also reducing the risk of reintroducing contaminants into the environment that could occur if purely dry methods were used.

Using soap and water only, soaking in water, or air drying are not sufficient for condition 3 situations, as they may not effectively eliminate microbial threats. Both soaking and air drying can permit the recontamination of surfaces and do not provide the level of cleaning required for the potential hazards typical of condition 3 scenarios.
