The answer to 'why is my bathroom mildew' is that mildew is a type of mold that thrives in warm, damp environments like bathrooms. Common causes include poor ventilation, leaks, high humidity, and insufficient cleaning. Symptoms include visible black, green, or white spots on surfaces and a musty odor. Mildew can pose health risks and should be addressed promptly.
To solve bathroom mildew, start by improving ventilation by running the exhaust fan or opening a window during and after showers. Regularly clean surfaces with a mildew-killing cleaner, and fix any leaks or moisture issues. If the mildew persists or covers a large area, it's best to call a professional cleaning service to properly treat and prevent future growth.
