The answer to 'vacuum moldy' is that vacuuming can be an effective way to clean up minor mold growth, but it should be done with caution. Mold can be harmful to your health, so it's important to take the proper precautions when attempting to clean it up yourself.
The key is to use a vacuum with a HEPA (High-Efficiency Particulate Air) filter, which can capture mold spores and prevent them from being released back into the air. You'll also want to avoid stirring up the mold and spreading it further, so be gentle and avoid aggressive scrubbing. If the mold covers a large area or is in hard-to-reach places, it's best to call in a professional mold remediation company to ensure the problem is properly addressed.
