Black mold is a living organism that thrives in damp, warm environments. The tiny spores grow in colonies on organic surfaces. While non-organic surfaces, such as the edge of a bathtub, alone do not provide a conducive location for mold growth, the dirt and dust on the non-organic material does. Unless the living organism is killed and removed, black mold will continue to thrive and spread to surrounding surfaces.
Black mold is a problem from the moment the first spore grows. Because the organisms are so small, musty odor is often the first telltale sign that mold is present. After the stale smell develops, mold begins to leave ugly black spots on the affected surface. People with respiratory conditions, compromised immune systems and allergies are especially sensitive to black mold. Symptoms commonly suffered by those who are sensitive to black mold include shortness of breath, skin and eye irritation and allergy symptoms.
To effectively get rid of black mold, you have to kill it before removing the stains. With the right supplies, you can wipe out the black mold while also getting rid of the smell and stains. One common remedy for removing black mold is a solution made from 1 cup of household chlorine bleach mixed in 1 gallon of water. If the smell of bleach bothers you, there are other alternatives for killing mold and removing the stain. Full-strength white vinegar or rubbing alcohol is effective, as is a mixture of 2 tablespoons of ammonia in 1 gallon of hot water.
Although opening up a window or door is an effective way to reduce poor air circulation, it isn't always possible. Draw excess moisture out of the air and regulate air moisture levels by using a dehumidifier. By drying out the air, you can also prevent mold from returning. Run an electric fan or your heating and air conditioning system to move the air around in the room. Air movement helps relieve odors that are hanging in the air.
