Blot the stained cloth
Begin by blotting with a clean cloth to remove as much of the stain as possible. DO NOT SCRUB. Your goal is to “lift” the stain and not rub it into the fiber.
Soak the cloth in cold water
Let the stained clothing soak in cold water. After the stain has soaked for a while, agitate it around to loosen the stain or you add a little bit of detergent if you want. If the stain is still present, you can try soaking it overnight in cold water. If that doesn’t work, proceed to the step below.
Make a saline solution
Make a solution of 1 cup of salt with 2 quarts of water. Let the stain soak in the solution for 30 minutes. If the stain is stubborn, use a mild bar soap and rub the fabric together with your hands.
Use hydrogen peroxide
If the stain persists, try dabbing a little bit of hydrogen peroxide on the stain and then rinse. Be careful with the hydrogen peroxide as it can wear down the fibers of your clothing similar to the way bleach does. It shouldn’t remove the colouring, but it will make the fabric weak.
Wash the cloth in cold water
When the stain is removed, wash the clothing in cold water and detergent recommendations on the care tag.
You may want to air-dry the clothing to be sure the stain is not noticeable when it’s dry. If you place it in the dryer and it’s not completely gone, it will be set from the heat and impossible to remove.
