If you are impatient, I found that putting shock granules in a paint strainer bag, tying a string around the bag and letting it sit on top of the stain wand dissolve with the pump off (so it doesn't disburse) will help expedite the removal of the stain. As another poster said, the stains will diminish over time, but letting shock dissolve directly on the stain helps WARNING: You have to be very careful with shock granules and don't dip it in and out of the water or get it on your skin. Nasty stuff.
