How to Get Rid of Armpit Stains?
To get rid of armpit stains you can first try making a paste out of water and baking soda and applying it to the stain. Let it sit for about 20 minutes then wash as usual. You can also try adding vinegar or bleach (if the fabric permits) to your wash load. One last remedy is to make a paste out of crushed up aspirin, apply to the stain, let it set over night, then wash as usual.
