Your skin is in direct contact with the collar of your shirt. It's little wonder, then, that when sweat and body oil accumulate on the fabric, ring around the collar is often left behind. This discolored portion of the collar is usually quite noticeable, so removal is important to keep your shirts in good shape. Treat ring around the collar at first sight; the longer you wait, the heavier the buildup and harder it is to remove.
Dish Soap
Regular laundry detergent often contains harsh chemicals that can damage some fabrics, so it’s not advisable to treat ring around the collar by directly applying it to the shirt. Instead, use dish soap. Drizzle liquid dish soap onto the stain and work it into the fabric with your fingers. Rinse the collar with cool water, and launder the shirt as usual.
Baking Soda and Vinegar
Baking soda and vinegar are staples in most kitchens, and you may as well make them regular fixtures in your laundry room as well. Ring around the collar is no match for this stain-fighting duo. Mix baking soda and vinegar in a bowl to form a paste; rub the paste on the collar stain. Let it sit for 30 minutes, then wash the shirt as usual.
