The answer to 'why is my kitchen mildew' is that mildew is a type of mold that thrives in damp, humid environments. Mildew can grow on kitchen surfaces like countertops, walls, and around sinks due to excess moisture, poor ventilation, or leaks. Common symptoms include a musty odor, visible white or gray powdery growth, and staining on surfaces.
To prevent and remove kitchen mildew, it's important to address the underlying moisture issues. This may involve fixing leaks, improving airflow and ventilation, using a dehumidifier, and regularly cleaning and drying surfaces. For small areas of mildew, you can typically treat it yourself using a mild bleach solution or commercial mildew remover. However, for larger mold infestations or persistent moisture problems, it's best to call in a professional cleaning service to properly assess and resolve the issue.
