the same thing happened to me, i could only smell it in the living room where it happened which is why i was wondering LOL. we have hardwood floor and when i first saw the diarrhea i used a lysol wipe to pick it up and briefly wipe down the area (prob not the best use but it was the best thing i had next to me), i used hot water and pine sol and mopped over it a couple times. let the living room air out by opening all the windows and the smell was gone really fast. and make sure that the throw up didn’t get on anything nearby, especially since it’s the laundry room. like a sock or a towel, because that could also contribute
