Use a scrub to scrub the closed area’s floor and walls. Pay particular attention to the corners. Let it stand for five minutes and give a rinse of cold water to get rid of the bleach entirely. Dry with a clean rag and let it completely air-dry by keeping the doors or windows open, or by training a fan directly inside the closed area. You can put charcoal briquettes or a box of baking in the closed area after you’re done to absorb any other smell that will arise in the future. Installing a dehumidifier or an electric air vent fan will discourage moisture from collecting in that area and encourage the air to move around. As a final touch, use an air freshener spray or Fabreeze to bring back a fresh smell in to the closed area that previously smelled like mildew.
You can also use small gel packs that absorb moisture in these closed areas. You may run into mildew odors with clothes that have been stored away for a long period of time. Here’s what you do with them: Hang them out to dry outdoors all day and bring them back in. Wash your clothes as you normally would, although using detergent products aimed for mildewy clothes will help a lot. Hang them out to dry in the sun again. Delicate clothing or fabric that’s been stored away shouldn’t just be thrown in the laundry.
Having these delicate fabric cleaned by a professional is still the best way to go. After laundering your clothes, pack them back in new boxes with dryer sheets in between the folded clothes. Replacing these dryer sheets regularly will keep the fabrics fresh and dry and discourage mildew from popping up again. Air ducts are also prone to having mildew because of moisture getting trapped and the lack of exposure to light. Having a forced air heating and cooling system can also encourage mildew to grow aggressively. If you have a mildew smell all around the house with seemingly no source, your air ducts may be a culprit. Having molds or mildew can cause allergy and asthma attacks, so have them checked.
Cleaning out air ducts are best left to the professionals. Make sure you hire a reputable company to do the work for you. Check their reputation online and ask for references if you can. Roofs bear the brunt of the force of nature, and mildew growth are one of the problems that may arise following this fact. Mildew on your rooftops and shingles can make your roof look dirty and even shorten the lifespan of your roof. Not only that, but a heavy mildew growth may cause mildew odor to gradually seep inside your house.
To get rid of mildew, you should first spray the plants immediately surrounding your area with water to prevent damage from the cleaning products you are about to use. Get a hand spray and fill a fourth of bleach and the rest with water. Directly spray the solution on the mildew. Let it sit for 15 minutes and hose it off with water. Be very careful when working on the roof, as wet mildew can get very slippery. Spray your plants again with water for protection.
Mix copper sulfate to water in the ratio of 12 dry ounces to a gallon of water. Apply the solution directly on the mildew and once it’s dried and turned brown, brush or scrub off. Once you’ve gotten rid of the mildew from your rooftop, it’s time for some preventive measures. First, get rid of the overhanging tree branches or debris that may have collected on your rooftop, which encourage mildew to grow. Second, you gave the option to install zinc strips under the shingles in the edge of your rooftop to discourage mildew growth. Third, you can install asphalt roofing shingles with a copper additive that when mixed with rainwater actually prevents the growth of mildew. Lastly, you can also buy commercial products that you can simply spray on your roof once a year to prevent mildew growth.
Carpets that have not been cleaned properly can lead to moisture being trapped inside the carpets, which can result in mildew. Short of taking them to cleaners, here’s something you can do yourself. It can also be effective for mildew growing under your wallpapers. Make a bleach solution made from one part bleach to ten parts water for mild mildew growth or one part bleach to four parts water for more intense mildew growth. Use tap water to wash down your walls or the carpet. Get a hot water carpet cleaner and put the bleach solution in the reservoir, adding a few drops of liquid dish soap. Let it stand for 15 minutes and rinse again using mop boards. Dry with clean rags, and let dry, either by hanging the carpets out, or in the case of wallpaper, open up windows and doors to let the air in. Use a fan to accelerate the drying process. In some cases of mildew growing in carpets, there’s a likelihood that the mildew has progressed into your floor again. You can try the same approach you did with your carpet, or use a latex seal to seal the mildew and the mildew odor out completely. Sink drains are also one of the spots where mildew can grow in abundance. The collection of scum and bacteria can also encourage further mildew growth, and make the odor worse. The mixture should foam and kill the mildew. Leave on overnight and rinse away by pouring hot water down the drain.
