The water is probably is not getting hot enough to dissolve them all the way. That's one thing that's kinda sucks about them bc some clothes can't wash hot. 🙃 I started making my own laundry soap , lasts sooo long
Are you using hot water? I've found the pods dissolve and disperse the best in hot water
I run hot water first to dissolve then switch to cold. Or if I really don’t want to use hot water for whatever reason I pop them myself and help them dissolve lmfao
It may be that the pod didn't fully dissolve and that's why the gooey remarks were left behind
