With the wet weather we’ve been experiencing in the Interior this latter summer, there is quite a bit of moisture on the ground- as well as a high ambient humidity. Pressure tanks from wells are often weeping condensation, windows may show signs of beaded moisture in the corners (especially early in the mornings) and on grass along walkways soak shoes that go off the beaten path, even when not raining. With such conditions, there are concerns with drywall and tile grout being growth areas for mold within homes, thus decreasing the air quality.
What can you do? The first thing to do once you detect mold is to stop the ambient moisture from collecting -especially in corners, transition of materials used and around sweating water tanks as well as pipes. Trays under pressure tanks or water treatment tanks can help. Towels around metal faucet bases that run water for considerable time help to reduce condensation. Even running a dehumidifier can help in daylight basements to assist to make the environment dryer.
Once locating the source of moisture and putting an end to it, killing the mold by applying a solution with a wet cloth is the next step- which may require a stiff brush and follow up with a clean damp cloth wiping the area down. Drying the clean area with a fan allows you to then use a primer (best if containing a biocide) to make the area resistant to further mold growth. The solution used to kill the mold early on depends on people’s preferences. Governmental agencies used to suggest watered down household bleach but there were concerns over respiratory reactions to the bleach. Some people use laundry detergent made into a slurry, while others suggest using mixtures of natural elements such as vinegar and baking soda. Read various reputable sources before making your own cleaning solutions or buying off-the-shelf solutions.
And most of all, keep the known troublesome areas as dry as you can with fans and open sources of air movement.
