Problem: Article: If you've lived in your home for a while, you probably know where most of the ducts are. Take some time to locate all of them anyway in order to save time. Some homes have vents high on the walls, and others have them located at the base of the walls. Plan to clean each one of these in a systematic fashion. Basically, clean them room-by-room—unless you want to skip around to make it last longer. Some vents might be located in unusual places. Roam around your house to locate them all. You'll probably find other things that need to be cleaned or fixed in the process, but don't get distracted. Check for anything underneath the duct, such as furniture, hanging pictures, carpet or rugs, decorative items, etc. Move them out of the way or cover them so that they don't get dust or dirt landing on them. You don't need another thing to clean. A ladder, step-stool, stable chair, or particularly strong person that can hold you up will work. Make sure that the item is sitting flat and does not wobble under your weight. Cleaner air is great, but it doesn't have to come at the cost of a twisted ankle. In basic terms, the supply registers are the things that supply heated air to the rooms. Lift the register, cover it in a paper towel, and put it back in place. It's as easy as that. This will keep excess dust from being released into the room while you clean the air ducts. Doing this will keep everyone in the house from inhaling and coughing up all the dust you're about to release. Go to your thermostat and turn the fan on. Turn the heat and cool mode off. You'll only want the fan to be running. Look at your furnace filter to make sure it isn't missing or damaged. The filter is important so that the dust you're about to clean out doesn't get stuck in the fan motor. That would create another problem. Use something similar to a toilet brush, but you probably don't want to use the toilet brush you already have. A fairly large, stiff-bristle paintbrush is ideal. Use that brush to knock loose the stuck or damp dust in the air vents.
Summary: Locate the air ducts in your home. Look underneath the ducts. Set up a stable surface to stand on if your vent is high. Cover the supply registers with paper towels. Turn on a fan in the room you're starting with. Check the filter. Loosen up the dust in the air ducts.

Problem: Article: An ingrown fingernail is a fingernail where one edge of the nail grows and curves into the soft skin around the sides of the finger. The resulting pressure causes redness, pain, swelling, and sometimes an infection.  If ingrown fingernails get infected, there may be pus and the swelling may extend along the finger. The ingrown nail can grow into the soft skin on either the inner or outer corner of the nail. Ingrown fingernails are rarer than ingrown toenails; however, there are a few things that lead to them. Causes of ingrown fingernails include:  Injury Nail biting Cutting the fingernails too short or unevenly Fungal infections Having curved or thickened fingernails, which may be due to genetics, but can be a problem in older people Most ingrown fingernails will heal with home or standard medical treatment. However, some infections may become severe. If your symptoms become severe, you should go to your doctor or the emergency room immediately. If your fingernail has pus, if the pain around an ingrown fingernail is getting worse, if the redness and tenderness spreads, if you cannot bend the finger at any of the joints, or if you have a fever, seek medical attention. You can try to prevent ingrown fingernails from occurring. Refrain from cutting your nails too short because this can lead to ingrown fingernails. You also should refrain from ripping or tearing your fingernails. File off any rough, uneven edges.  Make sure to keep your hands and nails dry. Keep your nails clean. Keep a watch on your fingernails to look for signs of ingrown nails so you can catch one early.
Summary: Recognize the symptoms of an ingrown fingernail. Learn the causes of ingrown fingernails. Monitor for worsening symptoms. Prevent ingrown fingernails.

Problem: Article: Cut a piece of lemon into individual slices that are small enough to fit into each section of an icecube tray. Fill the ice cube tray with vinegar. The vinegar will help deodorize and sanitize your garbage disposal drain. It will also clean out crevices in your garbage disposal sink. Leave the tray in the freezer overnight and allow all of the ice cubes to harden. Break the ice cubes out of the tray and dump them into your garbage disposal drain. Run cold water over the ice cubes and turn on your garbage disposal. The blades should break up the ice, and the citrus and vinegar should freshen up the smell and clean your drain. Once you're done, run cold water to rinse out the drain. Cold water hardens oils and grease so that the garbage disposal blade can break them up.
Summary:
Cut a lemon into slices. Put the slices into an icecube tray and top them with vinegar. Allow the ice cubes to harden. Place the ice cubes in your garbage disposal. Turn on your garbage disposal until you break up all the ice.
