Removing Armpit Stains (Step by Step)

Step 1

Combine 1/2 cup Dawn dish soap and 1 cup hydrogen peroxide in a small bowl. Stir to combine.

Step 2

Apply the soap and peroxide mixture to the stain(s), and sprinkle a bit of baking soda over the area.

Step 3

Use a laundry scrub brush or an old toothbrush to work the Dawn, peroxide, and baking soda into the fibers of the shirt. (Make sure to clean an area slightly bigger than the actual stain so you don’t accidentally miss any of it.)

Step 4

After scrubbing, let the clothing sit for at least an hour or so, and then launder as usual. I accidentally let this white shirt sit for an entire weekend before washing because I forgot about it, but it was completely fine and came out of the wash looking brand new!
