I have found this formula to be effective on most stains including grease, ink and grime. (Of course pre-test the solution on an inconspicuous part of the garment to make sure that the solution won’t damage the garment.)
1 t. Dawn detergent
3 – 4 T hydrogen peroxide
2 T baking soda
Scrub on with an old toothbrush and wash garment per washing instructions. My go-to washing method is to turn the garment inside out, wash in cold water with a detergent that contains no additives. I then put the garment in the dryer for 5 minutes, just long enough to soften the fibers, and then hang to dry.
The solution deodorizes the garment as well as lifts stains.
