Experts recommend using baking soda, vinegar, or bleach to effectively clean mold stains from walls. However, it is crucial to apply these substances carefully to avoid damaging the paint. The process focuses on removing visible stains while maintaining the surface integrity. Beyond simple cleaning, experts warn that these stains often signal a deeper structural problem. Humidity issues typically hide behind the visible mold, requiring more than just a surface-level fix. Addressing the root cause is essential to prevent the mold from returning. Consequently, a comprehensive approach to moisture control is necessary for a long-term solution.
