How can i tell if a surface has been properly cleaned of mold?

To detect mold and mildew and how to tell if your home has mold,. Do samples need to be taken to detect mold? In most cases, if there is visible mold growth, there is no need to take samples. Because no EPA or other federal limits have been established for mold or mold spores, samples cannot be used to verify that a building complies with federal mold regulations. Surface sampling can be useful in determining if an area has been properly cleaned or remediated.

Mold sampling should be performed by professionals with specific experience in designing mold sampling protocols, sampling methods, and interpreting the results. Sample analysis should follow the analytical methods recommended by the American Industrial Hygiene Association (AIHA), the American Conference of Governmental Industrial Hygienists (ACGIH), or other professional organizations. One of the best proven methods for detecting the presence of mold is to simply let your nose smell. Most of the time, a mold problem is easily identified by a musty smell that is evident in humid environments.

Mold also likes to play hide and seek, so if you suspect there's a problem, look under carpets, behind drywall, inside ducts, between bathroom tiles and other areas prone to moisture. David Ragsdale, production director at SERVPRO headquarters, says that other signs of possible moisture accumulation are bubble paint, uneven hardwood floors or discoloration of finished surfaces. Bleach or other disinfectants may need to be used on surfaces after removing mold when people are considered susceptible to fungal infections (such as people with immune system problems). When cleaning up mold on your own, be sure to use N-95 gloves, goggles, and respiratory masks to reduce your exposure to mold.

Mold sprouts from small spores that float in the air and settle on damp surfaces, where they reproduce in mold colonies. For non-porous surfaces, such as countertops, cabinets and vanities, simply clean them with water and dish detergent to remove mold. The use of a chemical or biocidal product that destroys organisms such as mold (chlorine bleach, for example) is not recommended as a routine practice when cleaning mold. In general, clean surfaces to remove condensation and dry standing water to prevent mold from growing.
