Mix one part glycerin, one part white dish washing detergent and eight parts water to make the wet spotter. Store the solution in a plastic squeeze bottle. Saturate the yellow stain with the spotter.
Yellow perspiration stains contain urea, which is soluble in ammonia. Put a few drops of ammonia on the moist garment to assist the spotter in loosening the stain.
Wet a white paper towel with the spotter, and place it on top of the stain. Allow the paper towel to draw out the stain. Check the stain regularly for removal. Keep the towel and garment wet by applying more liquid as necessary.
For delicate fabrics, choose the appropriate cycle on the washing machine, or hand wash and dry the garment following the directions on the manufacturer's care label.
