This is a 4th generation dry cleaner's guide to removing a white deodorant stain!
First start with dish soap and water (I like about 2-3 drops of dish soap and 2 cups of water) and work that in.
Next, you'll need a rust stain remover. This is the KEY element of deodorant removal as most deodorant stains are actually rust stains.
Let this stain pretreatment sit on the stain for at least 15 minutes before washing as recommended.
Make sure to inspect before tumble drying. If that did not work repeat the process and allow the stain treatment to sit on the stain longer (overnight is best).
If your stain is YELLOW at the underarm it is an oxidized sweat stain and will require oxygen bleaches. This guide will not help you.
I hope you found this helpful :)
