To eliminate mildew smell in the house, locate the source and clean it with a mixture of water and vinegar.
Ensure proper ventilation, use dehumidifiers to reduce moisture, and consider using air purifiers with HEPA filters to remove lingering odors.
Identify the Source of the Mildew Smell

Common Areas for Mildew Growth
Bathrooms, kitchens, basements, and laundry rooms are often the hotspots for mildew due to their high moisture levels.
Regularly inspect these areas for any signs of mildew or mold, paying special attention to corners and hidden spots where it might grow unnoticed.
Look behind appliances, under sinks, and around windows where condensation can encourage mildew growth.
Visible Signs of Mold and Mildew
Visual inspection is crucial in identifying mildew presence. Check your walls, ceilings, and floors for any discoloration, black or green spots, or fuzzy growths.
Wallpaper and paint may also show bubbling or peeling, which can indicate moisture issues and potential mildew beneath the surface.
Using Your Sense of Smell
Mildew emits a distinct musty odor that can help you track down the source. Trust your nose and move towards areas where the smell is strongest.
Sometimes, the scent may be concentrated in unexpected places like closets or behind furniture, so be thorough in your search.
Professional Mold Detection
If you’ve done a thorough inspection and still can’t find the source of the mildew smell, it might be time to call in a professional.
Mold detection experts have specialized tools and experience to uncover hidden mildew and provide solutions for removal.

Safety Precautions for Cleaning Mildew
Before you begin the cleaning process, protect yourself. Wear gloves, a mask, and protective eyewear to avoid direct contact with mildew and the inhalation of spores.
This safety gear will prevent allergic reactions or respiratory issues that can be triggered by exposure to mildew.
Natural Cleaning Solutions
Vinegar, baking soda, and hydrogen peroxide are effective natural cleaners that can kill mildew.
Mix water and vinegar in equal parts to spray on affected surfaces, apply baking soda mixed with water to create a paste for scrubbing, and use hydrogen peroxide in a spray bottle for tougher spots.
Always rinse the area with water after cleaning and let it dry completely.
Commercial Mildew Removers
When natural solutions aren’t enough, commercial mildew removers can be more effective.
There are sprays, gels, and foams designed for specific surfaces and levels of mildew infestation.
Always read and follow the manufacturer’s instructions to ensure safe and effective use.
Cleaning Process for Different Surfaces
Each surface requires a different approach. For tiles, use a stiff brush to scrub the vinegar solution into the grout.
Fabrics may be washed with hot water and detergent, adding vinegar to the wash cycle. Wood surfaces should be cleaned gently to avoid damage, using a soft cloth and a mild cleaner.
Preventing Mildew During Cleaning
Prevent mildew from spreading by keeping the area well-ventilated during cleaning. Open windows and use fans to circulate air and help surfaces dry faster.
This practice not only aids in removing the existing mildew but also helps deter future growth by reducing moisture.
Prevent Future Mildew Growth

Control Humidity Levels
Use dehumidifiers in damp areas of your home to maintain humidity levels below 50%. Fans and air conditioners also help by circulating air and reducing moisture.
Hygrometers can be used to monitor the humidity levels and ensure they stay in a range that is not conducive to mildew growth.
Proper Ventilation Practices
Always keep your home well-ventilated. Open windows when weather permits, use exhaust fans in bathrooms and kitchens, and have your HVAC system cleaned regularly to prevent mildew spores from circulating through your home.
Regular Maintenance
Fix any leaks in your plumbing or roof as soon as they’re discovered. Clean your gutters to prevent water buildup and ensure that any wet areas in your home are dried promptly.
These measures will help keep your home dry and uninhabitable for mildew.
Mildew-Resistant Products
Choose mildew-resistant paints, shower curtains, and building materials when renovating or repairing your home.
These products are designed to resist moisture and can be an effective part of your strategy to prevent mildew growth.
Lifestyle Changes for a Dryer Home
Small changes in your daily habits can make a big difference. Take shorter showers to reduce steam, dry clothes immediately rather than leaving them in the washer, and store items in a dry state to prevent mildew from taking hold.
By following these detailed steps, you can effectively identify, eliminate, and prevent the recurrence of mildew in your home, ensuring a healthier and more pleasant living environment.
