If your walls are turning black in a corner, it’s a clear sign that.

Without airflow, moisture can’t escape. This is common in bathrooms, closets, or corners blocked by furniture.

What You Should Do:
Inspect the area closely—peel back paint or wallpaper if necessary to see the full extent.

Clean the mold safely (wear gloves and a mask) using white vinegar, hydrogen peroxide, or a mold cleaner.

Fix the source of moisture—seal leaks, improve ventilation, or run a dehumidifier.

Repaint with mold-resistant paint after treating the wall thoroughly.

Tip: If the mold covers a large area (more than 10 square feet), call a professional mold remediation expert—it’s not safe to handle alone.
