Egyptian cotton is used in a variety of cloth items, such as sheets or shirts. The cotton is soft, breathable and comfortable. When sweat gets on Egyptian cotton, it can leave a yellow or yellow-brown stain. The stain looks ugly and does not come out in a simple wash. Fortunately, removing the stain is actually simple, especially if it is a new stain and has not yet set into the fabric.
Soak the Egyptian cotton in cold water. Avoid using hot water, which will cause the stain to set in. If the stain is a new stain, cleaning can start immediately after getting wet. If the stain is older than 24 hours, allow the cotton to soak in cold water for a while.
Remove the cotton item from the water and wring out the excess water so that the cotton is damp.
Apply shampoo directly to the stain. The amount will vary depending on the size of the sweat stain. Rub the shampoo into the fabric until it is completely absorbed and then rinse free.
Make a paste of baking soda and water. The amount of water and baking soda will differ based on the size of the stain, but a few tablespoons of baking soda with about half a cup of water should cover most stain areas. Apply the paste to the stain and let it sit for one hour.
Rinse the baking soda free. Repeat as necessary until the stain is removed.
Wash the Egyptian cotton as normal.
Avoid drying in the dryer until the stain is removed. Adding heat will cause the stain to set and makes it harder to get out.
