The answer to 'carpet mildew' is that carpet mildew is a common problem caused by excessive moisture, poor ventilation, or water damage. Symptoms include a musty odor, visible mold growth, and discoloration of the carpet fibers. To address carpet mildew, it's important to first identify and address the root cause of the moisture issue. This may involve repairing any water leaks, improving airflow and ventilation, or using a dehumidifier to lower the humidity levels.
For mild cases of carpet mildew, homeowners may be able to treat the affected area themselves using a specialized carpet cleaning solution or a mixture of water and white vinegar. However, for more severe or widespread mildew growth, it's best to call in a professional carpet cleaning service to properly clean and disinfect the carpet.
