Problem: Article: Expect the metal to oxidize and create mineral deposits over time, especially if it didn't dry thoroughly. Inspect the insides of the boiler and server for discoloration every now and then. Correct these by mixing one part white vinegar with eight parts water and using this to scrub out the inside, and/or let it sit overnight in the boiler. It's also important to do this in order to keep the boiler's overpressure valve clear of any deposits that may be blocking it. Dish soap dulls the pot's shine, but it's necessary to use occasionally in order to prevent coffee oils from growing rancid. If you miss that shine, don't worry. Whether your pot is aluminum or stainless steel, polish the outside as needed to restore its luster. Expect rubber gaskets to deteriorate over time. This means that an old gasket will form a less secure seal for the filter at the bottom of the server, which in turn means coffee grounds may end up where they're not supposed to be. Replace old gaskets as needed to ensure a clean cup of coffee.
Summary: Clean mineral deposits as needed. Restore the pot's shine. Replace gaskets.

INPUT ARTICLE: Article: All you need is a piece of paper and either a pen or a pencil it seems simple enough, right? However, poor quality materials can make a significant impact on the legibility of your writing. The page should be smooth not rough enough to catch the tip of your pen and create snags in the line of your letters, and not so smooth that the tip of your pen goes sliding about without your control. Use lined paper sized appropriately for your comfort level wide-ruled if you write large letters, college-ruled if you write small letters. Note that in many professional contexts, adults are expected to write within the limits of college-ruled paper, but feel free to use wide-ruled if you are still young and in school. Experiment with different types of pens to see which one works best for you. There are several styles, each with their own benefits and drawbacks. Fountain pens use liquid ink and have a flexible writing tip that allows for stylized, better handwriting. While it delivers a beautiful line, a good fountain pen can be pricey, and it takes a good deal of practice to perfect the fountain pen technique. Ballpoint pens use a paste ink which some find unappealing compared to liquid ink; however, they can be extremely inexpensive. Note that you'll get what you pay for with ballpoint pens a cheap pen will deliver poor handwriting, so it may be worth it to spend a little extra money. Rollerball pens have a "ball" delivery system much like a ballpoint pen, but many people prefer them because they use the higher quality liquid rather than paste ink. However, they don't last as long as ballpoint pens do. The gel ink used in gel ink pens is thicker than liquid ink and results in a smooth feel and line that many people enjoy. Gel ink pens come in a wide variety of colors but can dry out quickly. Fiber tip pens use a felt tip to deliver ink, and many writers enjoy their distinctive feel when drawn against a page smooth, but with a little friction or resistance. Because the ink dries quickly, these pens are a good option for left-handed writers whose hands smudge their words from left to right. The first step to developing good posture while writing is actually to use a good writing surface. If the table is too low, people have a tendency to slump down and round their spines, which can result in chronic pain and injury. If it's too high, people carry their shoulders higher than is comfortable, resulting in neck and shoulder pain. Sit at a table that allows you to bend your elbows at approximately a 90-degree angle when writing. Once you've found a table that will discourage you from slumping or hitching your shoulders up, you need to hold your body in a way that prevents the back, neck, and shoulder pain that can accompany improper posture. Sit in your chair with both feet flat on the ground. Sit up straight, keeping your back and neck as straight as possible. You can take breaks from time to time if the posture is difficult, but over time, the muscles will develop and allow you to maintain good posture for extended periods. Instead of dipping your head down to look at the page while you're writing, keep your head as straight as possible while casting your eyes down. This will still result in a slight dip of the head, but it should not be hanging down toward the page. Sit flush with the edge of the desk, then turn the page you're writing on until it sits at an angle somewhere between 30 and 45 degrees to your body. If you are left-handed, the top edge of the page should point to your right; if you are right-handed, it should point to your left. As you practice writing, make small adjustments to find the angle that feels most comfortable to you and allows you to write most legibly. The rise of computers and cell phones for written communication has had a significant negative impact on handwriting one study revealed that 33% of people have trouble reading their own writing. Another symptom of this decline is the infrequency with which people write by hand these days; if you don't stretch your hands to prepare them for sudden increase inactivity, you'll find yourself cramping up sooner than you'd like. Clench your writing hand into a gentle fist and hold the position for thirty seconds. Then spread your fingers wide and stretch them for thirty seconds. Repeat four to five times. Bend your fingers down so the tip of each one touches the base of each finger joint where it meets the palm. Hold for 30 seconds, then release. Repeat four to five times. Place your hand palm-down on the table. Lift and stretch each finger up one at a time, then lower it. Repeat eight to ten times.

SUMMARY: Gather the best materials. Find a good writing table. Develop good writing posture. Position the page at an angle between 30 and 45 degrees. Stretch your hands before writing.

In one sentence, describe what the following article is about: Sharks migrate to and from different areas depending on the time of year. Some areas have lots of shark teeth because large numbers of sharks travel around the shores often. For example, sandbar sharks are found in large numbers off the east coast of Florida in spring when they mate. They move north at the end of summer and have their pups, so areas like Delaware Bay have a large population towards the early fall. Look up shark populated areas and select a beach to search for teeth. Sharks live in salt water only (except bull sharks who swim up into freshwater rivers that connect to the ocean). So don't go looking in your local pond. Sharks are more common in hot, humid places such as Hawaii and Florida. Although they can also be found at the poles. Many coastal regions of states near the ocean like California, Florida, Hawaii, Virginia, Carolina, and Alabama were once underwater. You can sometimes even find shark teeth fossils in these areas on dry land or in river beds since large portions of the state were submerged. Sharks were often drawn to these shallow waters to seek food. Big storms can bring in all sorts of debris from the ocean, including shark teeth. There will also be fewer visitors on the beach on days when the weather is less than ideal. Go in the morning when there are fewer people in the water. The calmer waters will make it easier to see any shark teeth. Weekdays are usually a less popular beach time, so go then if possible to avoid the crowds. You won't find a shark tooth in five minutes. Be prepared to stay at the beach for a couple of hours. Bring sunscreen and some water to stay there properly without harm. You may also want to pack a picnic lunch. People may be able to tell you about shark tooth hot-spots or places where they commonly found teeth. If you aren't from the area, a local may be able to tell you which beaches draw crowds and when, and which ones have a lot of teeth. You can improve your chances of finding teeth right away if you find someone that can point you in the right direction. Depending on what state or country you are looking for shark teeth in, you may need to get a permit before searching for fossils. In some areas, permits aren't necessary for shark teeth, but you never know what else you might find.
Summary:
Learn about shark migration patterns. Find a beach. Go after a storm. Start early. Be prepared. Ask locals to help you find the best spot. Get a permit, if necessary.
