I came across a 'recipe' [[if you call it that?]] for a paste made up of baking soda and hydrogen peroxide that supposedly blasted out the stain. So what could I do but try it?
Here is that journey:
|Mix Baking Soda and Hydrogen Peroxide to form a paste [[just eyeball it]].|
|Apply paste to desired area.|
Soak in a bucket of hot water for 30 minutes-1 hour.
Wash as normal.
