Because lily pollen is heavy in pigment, it creates a stain that is harder to remove than those created by other types of pollen. If left untreated, it will permanently stain your fabric; however, before you throw the fabric in the wash or try to rub the stain out, know that you could cause more harm than good. In fact, as a rule, never rub any kind of pollen stain. Fortunately, there are several methods that can successfully remove a lily pollen stain and the sooner you can treat it, the more likely you will succeed.
Shake the fabric gently to remove as much of the lily pollen as possible.
Remove any remaining pollen with tape. Use the sticky side to gently dab the pollen off the fabric.
Hang the fabric in the sun for about three hours. This may remove any remaining stains.
Soak the fabric in cold water for 30 minutes if the stain has already set in. Then rinse the stain off. Repeat this two more times, if necessary.
Spray the stain with a spray stain remover, such as Shout, if the stain still remains after rinsing it in cold water three times. Launder the fabric in hot water using an enzymatic detergent, such as Era, or oxygen bleach. If the fabric is not washable, rinse the stain once more and reapply the stain remover and rinse by hand until the stain is gone.
