In one sentence, describe what the following article is about: Often, nasal polyps do not show symptoms, and you may live your whole life without knowing they are there. If polyps grow larger, however, you can experience complications that will require medical attention. If you have the following symptoms, you should visit the doctor and see if you are suffering from nasal polyps. If they test you and confirm that you have polyps, there are some medical treatments they may recommend.  An excessively runny or stuffed up nose. Decreased sense of smell and taste. Pressure on the forehead or face. Feeling like your nose is clogged when mucus isn't present. Headaches. Pain in your upper row of teeth. Steroid sprays can help to reduce the size of your nasal polyps. If the polyps were small enough, they might disappear completely when treated with steroid sprays. Some steroid sprays are sold over the counter at pharmacies, but stronger varieties are available with a prescription. Talk to your doctor about using a steroid spray and see if it would work for you. Some of the common nasal sprays include beclomethasone, budesonide, fluticasone, mometasone, and triamcinolone. Nasonex is the most common brand name for steroid nasal sprays. Nasal drops, like nasal spray, help to shrink your polyps. Nasal drops can also clear up congestion, which can help you to breathe more easily while your polyps shrink. Most nasal drops take between 7 and 14 days to begin reducing polyps, and it is generally recommended that you continue to use them for another four to six weeks. When administering nasal drops, you should bend fully forward and downward. You should almost feel like you are about to try to stand on your head. Put the drops in your nose while your head hangs down. Keep your head down for 3 to 4 minutes after administering the drops to make sure that the drops reach your nasal cavity. Prednisone is an oral corticosteroid that reduces swelling and inflammation. It can help treat the inflammation in your nose and thus reduce the size of your nasal polyps. You can only get this steroid through a prescription from your doctor. Normally, you would take the steroid for 7 to 10 days. While antibiotics won't help reduce your polyps, they will treat complications that could result from polyps. If polyps block the sinuses, they can cause a sinus infection because the trapped bacteria will multiply. If you have a sinus infection from your polyps, your doctor will probably prescribe antibiotics to fight the infection. While these previous treatments will help shrink your polyps, usually the only way to get rid of polyps completely is with surgical removal. If polyps are persistent and causing significant discomfort, your doctor will probably suggest this option. To surgically remove nasal polyps, you will most likely have to get endoscopic sinus surgery. An endoscope—a long tube that has a light and video camera at the end—will be inserted in one of your nostrils and several tools will be used to remove your nasal polyps. You will be placed under general anesthesia during this operation. Usually you are well enough to go home the same day as your surgery. Remember that in some cases, the nasal polyps will return after two or three years.
Summary: Visit the doctor if you have symptoms of nasal polyps. Use steroid sprays. Try steroid nasal drops. Take prednisone. Take oral antibiotics. Consider surgery.

In one sentence, describe what the following article is about: Before you remove rust, make sure that the knife is free of dirt and oils. You can just hold your knife under some warm running water to clean it. Work slowly and be patient – if you rush the job, or scrub too vigorously, you risk damaging your knife.  Use regular water to clean away any dirt or stains. Be sure to wipe away all traces of fingerprints, as the natural salts present in human skin can cause a blade to rust. Avoid getting water into the gaps between the handle and blade, where it may create new rust spots that are difficult to reach. Thoroughly dry your knife with a soft, clean rag after you finish cleaning it. White vinegar contains acetic acid, which will often dissolve rust. Dampen a rag with white vinegar and apply it directly to the rust spots, or soak the blade in a shallow bowl of white vinegar for tougher stains. Once the rust has dissolved, rinse the blade thoroughly with water to remove the vinegar. Then, dry off the knife with a clean, dry cloth. Lemon juice can dissolve rust stains on metal surfaces, but it may work even better when you use it with some salt or baking soda. Try using a mixture of lemon juice and salt or baking soda to remove rust stains from your knife blade.  Sprinkle baking soda or salt onto the rust spots, then wipe the blade with a clean rag soaked in lemon juice. Rinse away the lemon juice with warm water after a minute or two and then dry it with a clean cloth. Be careful not to leave lemon juice on your blade for more than a few minutes, because it can damage the metal. Baking soda can remove rust stains, although you may need to repeat the process several times. Baking soda is used in cooking and for many house cleaning chores – you may already have some in your kitchen.  Make a thick paste by mixing baking soda with water. Put about a quarter (1/4) cup of baking soda in a glass bowl, and add a small amount of water to create a paste. Continue to add water in small increments, until you have a paste that is thick enough to stick to the surface of the blade. Apply the paste to the blade, and allow it to soak for two to three hours. Scrub the paste off of the blade with a wire brush or fine steel wool to remove the rust spots. Rinse away the rest of the paste by holding the knife under running water. Then, dry the knife thoroughly with a clean cloth. A raw potato may remove rust stains from metal surfaces. Potatoes contain oxalic acid, which can dissolve rust.  Stick the rusted blade directly into a potato and leave it there for a few hours. Then, remove the knife from the potato, rinse away the potato juices, and dry the knife with a clean cloth. Throw away the potato after you are finished with it. It might have small pieces of rust stuck in it, so it is not suitable for eating. Dishwashing soap mixed with vinegar can also remove rust stains from a knife. Get some regular dish soap and mix it with white cooking vinegar, or clear cleaning-grade vinegar.  Mix one part dish soap with one part vinegar, and apply it to the blade with a soft rag. Then, rinse away the solution and dry off the knife. For stubborn rust stains, soak the blade in the vinegar dish soap solution for an hour. Then, remove the blade and rinse off the vinegar dish soap solution under running water. Dry off the blade with a clean, dry towel.
Summary:
Clean your knife with water. Soak your blade in white vinegar. Apply some salt or baking soda and lemon juice. Use baking soda. Stab the rusty knife into a potato. Mix white vinegar and dishwashing soap.
