She says that the green area close to the property blocks sunlight and helps retain humidity in the apartment. The problem raises direct health concerns. "I've always had asthma since I was born. I have breathing problems, I'm quite allergic," says Camila. The professor of the Chemical Engineering course at the University of Caxias do Sul (UCS), Camila Baldasso, explains that the fungus is always present in the air, but needs specific conditions to grow. "We have the combo: heat, dust, fungus, which is mold, and humidity that comes from this process." To control the spread of mold, the expert recommends keeping the house ventilated, opening opposite windows for 15 to 20 minutes on sunny days. She also suggests practical strategies for cleaning and prevention: Alcohol vinegar: the recommendation is to spray the pure product on the area with mold, leave it to act for about an hour and clean with a damp cloth. The use of gloves and mask is mandatory. Bleach: recommended for tiles and glass, and should be avoided on porous surfaces. The product needs to be diluted in water in a one-to-one ratio. Requires the use of gloves and a mask due to toxicity, especially in closed environments such as bathrooms. Calcium chloride: chemical beads that suck moisture can be placed in small pots inside closets. Dehumidifiers: electronic devices that remove moisture from the air are also options, although they require greater financial investment.
