How do you remove semen from a girls Polyester Nightgown?

lol I don't want to go into details on how this happened, kind of a Christmas incident, any-who. The night gown is 100% Polyester.

I did something that appears to have been a dumb idea, I tried wetting it and using paper towels to soak it up and rub the stain out a little, and that didn't do anything really.

So that idea doesn't work.

um u shuld open the washer door put the gown in close the door add detergent and press start.

Wash it in the washing machine with some laundry detergent. Dry it on delicate (warm) and put it back where you found it.

put it in the washing machine :-)!?
