Article: For thick buildup on porcelain surfaces, you’ll need to use something a little more heavy-duty. Use a product like Comet or Ajax that comes in powdered form. The small particles will be able to penetrate deeper into stains that have set up on the surface of the tub to remove them.  Powdered cleansers contain chemicals known as surfactants which have mild abrasive properties. This makes them much more effective for addressing hardened, stuck-on residue.  Apply abrasive cleansers sparingly. For most jobs, a single canister be enough for a single thorough cleaning. Alternately, tough stains like rust and hard water residue can be treated with a mixture of hydrogen peroxide and cream of tartar. Blend the two ingredients together until they're about the same consistency as cake frosting and spread them directly over the stains. After 10 minutes, buff the stains with a nylon brush or pumice stone until they're erased completely.  Homemade concoctions like hydrogen peroxide and cream of tartar will be preferable for those who are wary of the health and environmental effects of chemical cleaning products. Hydrogen peroxide will also help treat age-related discoloration and lighten the finish of the tub. A moderate dusting should be enough to deal with most messes. The powder won’t stick to the surface of the porcelain on its own, but when combined with a liquid it will form a paste that can be spread directly over stains. Be sure to cover the bottom of the tub, where accumulated mold can become a slipping hazard. Spray purified or ordinary tap water onto the cleaning powder. With the addition of moisture, the powder will take on a thick, foamy consistency. Rub this paste into the stains and give it about half an hour to take effect.  You can also wet a clean sponge or washcloth and use it to rub in the cleaner until it thickens.  Another option is to wet the tub before you apply the cleanser. Spray the tub with the shower head or fill a cup with water and pour it around the inside of the tub. Be careful not to add an excessive amount of water. The cleaner won’t be as effective if it’s too thin. Since porcelain has a hard, durable finish, you can scrub it safely with an abrasive implement without worrying about scratching it up. For best results, equip a pumice stone or stiff-bristled scrubbing brush. Work on the stains until they’re completely erased, then rinse the tub with clean water and let it dry before using it again.  If you don’t own a dedicated scrubbing brush, you can use the rough green side of a kitchen sponge. Never use steel wool or any similar material to scour a porcelain tub. Even though porcelain is scratch-resistant, this can be enough to cause permanent damage to the finish.
Question: What is a summary of what this article is about?
Pick up a canister of abrasive cleaning powder. Stick with natural alternatives. Sprinkle the cleaning powder around the stained tub. Add enough water to produce a paste. Scour the stains with a sturdy scrubber.

Problem: Article: Stir for one minute. As the water evaporates, the water will boil more furiously, and that's when it begins to caramelize.
Summary: Place 6-oz ramekins in a deep baking dish and keep to one side. Pour 1/2 cup sugar into a clean saucepan. Add enough water to dissolve the sugar, and put the pot over high heat. Mix the caramel around to ensure it caramelizes evenly. Pour the caramel into the ramekins you prepared earlier; do this when you see the caramel has turned dark brown. Divide the mixture so that the bottom of each ramekin is covered with an even thin coat of the caramel.

INPUT ARTICLE: Article: You can buy scissors meant for hair cutting at a beauty supply store. Don't just use paper or nail scissors - they're too dull for your hair and will make awkward cuts. Make a conservative estimate of where you want your bangs to fall. Remember, you can always trim more, but growing back the hair that you didn't mean to cut takes a lot longer. Secure non-fringe hair so that it's away from your face and out of the danger zone.  If necessary, use a comb to part your bangs away from the rest of your hair. Splash a bit of water on the hair, or use a spray bottle.  They'll cut more easily wet, and you can do a touch-up once they dry. Grab a section of hair between the index and middle fingers of your non-dominant hand. Drag your fingers down so that they're resting just above where you want to make a cut. Put your scissors close to your fingers (so that they're almost parallel) and cut slowly. Your fingers (and the hair they're holding) should remain stable as the trimmed hair falls away. If you want your bangs to be the same length all the way across, make sure they match up.  On each side, grab a strand between the thumb and forefinger of each hand.  Pull your fingers down slowly and at the same pace. If one hand runs out of hair before the other, you need to trim a bit to match up the sides. Do this until you're satisfied that the lengths are even. If you want your bangs to sweep to the side, comb them in the direction that you want them to go.  Tip your head forward slightly, so that your bangs fall away from your face.  Put your scissors in the direction you want your bangs to run. Starting near the part, position the scissors where you want the shortest part of your bangs.  For side swept bangs, they'll get a bit longer as you go on.  Because of this, angle your scissors slightly downward. Make short, small cuts across your bangs.  The lengths should be a bit choppy, but not overly so.  Aim to cut sections that are about 0.5 inch (12 mm) wide. When your bangs dry, touch them up.  Ruffle the hair a bit, and see if you're happy with where it falls.  Make more trims if necessary.

SUMMARY: Get a sharp pair of scissors. Decide how short you're going to trim. Pull back the rest of your hair. Wet your bangs. Measure where you want to cut. Trim the hair beneath your fingers. Make sure your sides match up. Cut side swept bangs (optional).

Find a sterile bottle that's large enough to hold the water and pour 4 cups (0.95 L) of warm tap water directly into it.  To sterilize the bottle, boil it in water for 5 minutes or run it through your dishwasher on the hottest setting. Although tap water is safe to use, you can also use distilled water. The water should be comfortably warm, somewhere between 98 and 104 °F (37 and 40 °C). Use a measuring spoon to drop the table salt right into the bottle with the warm water. It's important not to eyeball the amount of salt or the solution might not be the correct strength. Ensure the cap is screwed on tightly so no water leaks and vigorously shake the bottle until you see the salt dissolve in the water. This should take around 30 seconds. The saline solution will be clear since there's very little salt in comparison to the water. Your doctor should tell you how much saline solution to use, but adults, in general, will need to pour 2 cups (470 ml) of the solution into the bag. Kids between the ages of 6 and 12 should get 1 1⁄2 cups (350 ml) of saline solution while children between the ages of 2 and 6 should use 3⁄4 cup (180 ml). For an extra laxative effect, your doctor might recommend adding 2 to 6 teaspoons (9.9 to 29.6 ml) of glycerin or prescription medication to treat bowel conditions, such as inflammatory bowel disease or ulcerative colitis. Follow your doctor's prescription when adding these medications to an enema. You may need to hold them longer or take them at specific times of the day.
