In one sentence, describe what the following article is about: Before submerging the hat in water, you need to see if the dye will run. Dip a white cloth in warm water and rub it on a small, inconspicuous area of the hat. If the dye comes off on the rag, don’t wash or submerge the hat. If it doesn’t, the item is colorfast and can be washed. Buy a new hat instead of trying to wash one that isn’t colorfast; the hat will likely be ruined if you do try to wash it. Put the soap in the bottom of the bucket or sink and allow it to fill up with warm water. Agitate the water to make bubbles. Avoid using a detergent containing bleach or a bleach alternative, which could fade the color of the hat. Before placing the hat in the water, you should pre-treat the stain. Spray a stain treatment product directly onto the fabric, concentrating on the areas that soak up the most sweat, like the interior band. Dip the hat in the sink or bucket and swirl it around several times. Then, let it soak in the water for a few hours to allow the soap to break down the sweat and oil in the fabric. You can stir the water or swirl the hat around every hour or so, if desired. Remove the hat from the bucket or drain the water from the sink. Use cold, running water to rinse the sweat and soap from the hat. Continue rinsing until the water runs clear and there are no more bubbles. Gently squeeze out the excess water, taking care not to ruin the shape of the hat. Roll up a small towel and place it inside the hat. Reshape the bill, if applicable. Then, place the hat near a fan or open window so it gets as much air flow as possible. Let it dry fully before wearing it again, which could take up to 24 hours. Avoid letting the hat dry in direct sunlight, which could fade the color. Don’t dry the hat in the clothes dryer either, which may shrink or damage the hat.
Summary: Find out if the fabric is colorfast. Fill a  bucket with warm water and 1 US tbsp (15 ml) of laundry detergent. Spray a stain treatment product on the hat to loosen sweat and grime. Let the hat soak in the soapy water for up to 4 hours. Rinse the hat thoroughly with cold water. Stuff the hat with a towel and allow it to air dry.

Problem: Article: Take off your shirt and stand in front of a mirror. Holding your breast at the edge of the areola (the dark area of skin surrounding the nipple) between your thumb and forefinger, press inwards about an inch behind your nipple. Be firm but gentle. Depending on the nipple's response, you can assess the grade of inversion.  Grade 1: The nipple protracts easily when you apply light pressure to the areola. When pressure is released, the nipple maintains its projection, rather than retracting immediately. Grade 1 inverted nipples are unlikely to interfere with breastfeeding, though you still may have cosmetic concerns. There is little to no fibrosis (excess connective tissue) in Grade 1 inverted nipples. Grade 2: The nipple protracts when pressure is applied, though not very easily, and retracts as soon as pressure is released. Grade 2 inversions are more likely to complicate breastfeeding. There is often a moderate degree of fibrosis, with mild retraction of the lactiferous or milk ducts. Grade 3: The nipple is retracted and does not respond to manipulation; it cannot be pulled out. This is the most serious form of inversion, with a significant amount of fibrosis and retracted milk ducts. You may also experience rashes or infections if you have Grade 3 inversion, and breastfeeding may be impossible.  Test both nipples, since they may not both be inverted. If you have had inverted nipples since childhood or puberty, your nipples are unlikely to be indicate an underlying problem. If they have changed recently, especially if you are over 50, they could indicate an illness or infection. Cancer and other serious conditions like inflammation or infection can occasionally cause inverted nipples.  If you are over 50 and your areola appears distorted and your nipple appears flatter than normal, or has become inverted, get screened for breast cancer immediately. Women over 50 are at risk for developing Paget's disease of the breast. Pink discharge and crusting, thickening, flaking, or scaling of the skin of the nipple and areola can also be symptoms of breast cancer. See a doctor if you have dirty white, greenish, or black discharge from your nipple. Tenderness, redness, or a thickening around your nipples may be a sign of mammary duct ecstasia. Perimenopausal women are especially at risk for mammary duct ecstasia. If you develop a painful lump that oozes pus when pushed or cut, and if you have fever, you may have a type of infection called subareolar breast abscess. Most nipple infections happen during lactation, but subareolar breast abscesses appear in women who are not lactating. If your nipples have been recently pierced and have become inverted, ask your doctor to check you for subareolar breast abscess. The treatment method depends on the grade of your inversion, the cause of your inversion, and whether you are planning to breastfeed. If you have signs of breast cancer, infection, or mammary duct ecstasia, visit your doctor immediately.  If you have Grade 1 inversion, it's likely that manual methods can help loosen the fibrous tissue and allow the nipple to protract more easily. If you have Grade 2 or 3 inversion, it may be a good idea to consult a doctor for your treatment plan. In some cases, non-invasive methods may be adequate, while plastic surgery may be a better option in others. If you are pregnant or nursing, be guided by your doctor, nurse or lactation consultant.
Summary:
Determine the grade of your inverted nipples. Identify the cause. Decide on a treatment method.
