In one sentence, describe what the following article is about: They'll protect your skin from the chemicals and irritants in many calcium removers. Make sure they're free of dirt before you start to clean. Use gloves that cover all or most of your forearm, in case the cleaner splashes. You can skip this step if you're using vinegar. Mix one part calcium remover, such as CLR, and one part water in a bowl or old plastic container. Choose a container bound for the recycling bin. For most taps, 1 to 2 tablespoons (15 to 30 mL) of each ingredient is enough. If you don't have much calcium buildup, you can use undiluted white vinegar instead of CLR and water. This method will take much longer, about 24 hours, but it's harmless to bare skin and safe for most faucet finishes. Avoid using calcium remover or vinegar on iron or nickel faucets. These cleaners will remove the finish along with the gunk you're cleaning. Read your owner's manual or contact a local plumber for advice. Use a regular-sized sandwich bag. It doesn't matter if the baggie has a zip seal. Pour carefully. If you're concerned about spilling the mixture, pour it into the baggie through a funnel. Hold the baggie at a slight angle so that the mixture builds up in one of the corners. Carefully slide the open end of the baggie over the faucet. Then submerge the tap in the mixture. Securely fasten the baggie to the faucet with a rubber band. Let the tap soak for one to two hours. Undo the rubber band. Carefully slide the baggie off of the faucet. Do this slowly. Read the label on the cleaner to check for disposal instructions. Cleaners like CLR are biodegradable and can be poured down the drain or toilet. Use an old toothbrush or magic eraser. Scrub in a gentle back-and-forth motion. Periodically rinse the toothbrush or magic eraser if it gets too gunky. Continue to do this until the buildup is completely removed. Move in a gentle circular or back-and-forth direction. Pay special attention to the tap to slow future calcium buildup. Continue until the faucet is completely dry.
Summary: Wear rubber gloves. Dilute calcium remover in water. Pour the mixture into a plastic baggie. Attach the baggie to the faucet. Remove the baggie. Scrub off the loosened buildup. Dry the faucet with a microfiber cloth.

At this point, side (1) should be crossed under side (2) a few inches in front of your body. Take end (1) and pass it up and over side (2). Pass end (1) through the large gap that you formed when overlapping the two sides of the obi. Leave the knot loose as you're forming it. Do not try to tighten the knot until it's completed, or you'll have a very difficult time completing the knot. Keep one of your hands on the point in front of you where sides (2) and (1) overlap, and use your other hand to guide side (1) of the belt through the gap where you put its tip in the previous step. As you pull side (1) through the gap, keep it flat. Don't allow the fabric of the belt to twist or fold, or you'll end up with a messy knot. Once you've pulled side (1) through the gap, the knot is ready to be tightened. Don't try to tighten the obi knot by pulling one side up and one side down, or you'll risk skewing the knot and giving it an asymmetrical look. The tightened knot should have a roughly diamond-shaped appearance.

One-sentence summary -- Tuck end (1) through the gap in the knot. Guide the rest of side (1) through the hole. Pull both sides outward to tighten the knot.

Q: The user manual should be written for the audience -- those who will be purchasing your product or service and reading the user manual. An audience analysis will tell you who your main or target audience will be and will guide your writing. Talk to people who will use your device. Offer test users prototypes of the device and a draft of the user manual under controlled conditions. Solicit these test users' feedback about things that are not obvious or confusing in the user directions and incorporate changes into your user manual based on this feedback. You can never please your entire audience; write the manual to suit the target or largest audience. Think about the audience's age, health (do they have illnesses, learning impairments, or disabilities?), and educational level to determine the best approach to writing the user guide. If you were part of the team that helped design and develop the device or product, it might be hard to look at the product objectively in order to explain its operation. You might, therefore, want to solicit the advice of a writer (preferably one with experience in writing instructions) and graphic designer in order to help you draft the user manual. You could choose these individuals from an outside consultancy or from your own company or organization. A task analysis is the process of identifying and organizing the steps needed to use the device. A thorough task analysis will identify the materials and equipment (such as batteries, medications, or other user-provided products) needed for each step, as well as the actions, errors, and troubleshooting advice that each step might require. If you have a product that can perform many different tasks or sub-tasks, you will need to perform a task analysis on each task. For instance, in a car, you can honk the horn, strap yourself in, and turn your headlights on or off. Create a task analysis for each of these as needed. These requirements ensure that products are produced with user safety in mind, and will limit user exposure to dangerous conditions such as radiation and electrocution. Advertisements must demonstrate clearly what the purpose and basic operational guidelines of a product are, and you should use these sources when writing your user manual. For the user manual of a product to be effective, it needs to be written in concert with labels affixed directly to the product. Ensure your device is legally licensed for sale before writing instruction manual. There are several important ways you can streamline your manual. You should place a bold heading at the start of each section with each word capitalized. For instance, "Setting Up Your Device," "Operating Your Device," and "Troubleshooting" could all be bold section headings. Another way to streamline your manual is to use two columns, one on the right with text and the other just to the left of the text with bullet points, numbers, or small icons like warning signs or red exclamation marks. Your manual might be mostly images with some text beneath each image to explain the device, or it could be primarily text with only a few accompanying images. You could also use a flow chart to provide the user with directions. Think about your product and how each method might be of use when writing your user manual. However, avoid mixing different layouts within a manual. Choose one and stick with it.
A: Do an audience analysis. Coordinate the design of the user manual. Do a task analysis. Ensure your product complies with labeling and marketing clearance requirements. Decide on your manual's layout.

Problem: Article: Choose a large decorative tray that's wide enough to hold your necklaces length-wise. Lay them out in a row in the tray, organizing by color or style as you go. The tray doesn't need to be made for jewelry. Try using a vintage serving tray, for instance. No matter where you buy jewelry, you often end up with small cardboard boxes. Use paperclips to attach them together. Set 2 bottoms side-by-side, and put the paperclip over the joined edges. Lay the boxes out in shallow drawer or tray. Place a necklace in each jewelry box. It's fine to let costume jewelry be out in the open, but you should protect more expensive jewelry from dust and damage. Place each necklace in its own jewelry box, and put the boxes away for safe keeping. You can also use jewelry boxes that have individual spaces for necklaces. Many of these are decorative and will look lovely sitting on a dresser or vanity.
Summary:
Pick a decorative tray for an easy way to lay out necklaces. Organize necklaces in the cardboard boxes the jewelry came in. Hide more expensive pieces in individual jewelry boxes.
