Lily flowers such as Asiatic and other types of lilies have pollen in the middle that, when brushed against, transfers to your clothing in the form of a yellow or orange stain. Pollen is crucial to the flower's reproductive process and one small pinch of pollen contains thousands of pollen grains. When a lily-pollen stain ends up on your clothing, the natural response is to want to brush it off but doing so can actually cause the pollen to go further into the fibers of the clothing, making a more difficult-to-remove stain.
Take off the clothing that has been stained by lily pollen. Carry the clothing outdoors and shake it out. Shake the clothing vigorously to remove as much pollen as possible.
Place the clothing, with the pollen stains face up, on a flat work surface. Roll an adhesive lint roller over the pollen to lift it from the fabric. Remove the adhesive lint roller sheet as it becomes covered with pollen then roll it over the clothing more until you've lifted as much of the lily pollen as possible.
Soak the lily-stained clothing in a bucket of cold water for 30 minutes to loosen any pollen stains deeper in the clothing's fibers. Remove the clothing from the bucket and wring out the water.
Squirt pre-wash stain remover onto the remaining lily pollen stain, using enough to cover the stain. Rub the pre-wash stain remover into the stain with your fingers. Let the pre-wash sit on the pollen stain for 15 minutes.
Fill the wash machine with the hottest water allowed for that particular fabric. Add laundry detergent with enzymes, using the recommended amount. Enzyme detergents are known for effectively removing pollen stains from clothing.
