I have never found anything that would remove lily pollen....
I am now very careful to remove the nathers as soon as a lily opens.
I carried an Easter lily home from church in my quite new car......the yellow stain stayed for 8 years until I traded it.

Lilies are famous for this. When you get them, immediately cut off the dark red/orange stamens over paper towels or newspapers. When new buds open, do the same thing. I use a small embroidery or manicure scissors. The pollen can be removed by a good dry cleaner. I have never found an at-home cleaning method that worked. If you get it on your clothes, above all don't brush it in or try to wash it off--only gets worse. Take it to the cleaners.

Blot from outside stain toward middle with white rag and denatured alcohol or dry cleaning fluid.

Surpisingly, sunlight does work. It bleaches the pollen stains right out after a day in the sun. I wouldn't have believed it until I tried it myself. However, I don't know whether it would work AFTER the garment has been laundered.

It's worth a try, and it's free!

Metaphysician, you are a genius! I tried to soak my shirt in everything known to man and finally stuck it out in the sun. Two hours later stain was gone!!!
