Rinse thoroughly. Every time you rinse, you are gently removing more of the stained area, so be sure to rinse completely. Rinse from the back of the stain. Repeat the previous steps. Repeat steps 2-4 until as much of the pollen stain as possible is gone. Use a spot stain remover. If you still see pollen stain or residue, apply a spot stain remover stick, spray, or gel.
