Weird question I know but my son peed his pants as he was sitting on the sofa most of the pee got on his pants but a little bit got on the sofa well I have sofa covers and I know I could just wash them but I want to know if it's necessary because I just washed the covers on Saturday barely 2 days ago I don't Wana waste water soap and time since I'm doing other laundry right now if it's not necessary should I was the cover or no ?

Please any advice.
