I am consistently cleaning my house. I recently noticed that the air vents in my guest powder room were truly dirty; Recently, my associate and I had some guests from out of village to stay with us. Midway through their visit, they both came down with a nasty cold. My associate and I figured the chilly was entirely due to lack of sleep and other factors that were travel related. They had to travel 9 hours to get here, so the jet lag and the weather difference would be enough to attribute to an illness. It was not until after they left that I noticed that there was mold growing on the inside of the air conditioner vents in the dining room and powder room where they stayed in our home. I instantly took the air conditioner vents off of the ceiling and threw them away. I found updatement vents online and purchased them. I wanted to make sure all of the mold was gone and that no more illnesses would occur as a result of this mold. I looked online and learned that the only way to get rid of mold completely is to use hydrogen peroxide and then bleach it away. I got a bottle of peroxide and climbed a ladder up into the air ducts. They were so dirty that I even needed to bring a steamer and a roll of paper towels to help get the task done. Thankfully, everything was resolved and the mold has not returned in the air vents.
