I don't know how they work, but these are great for getting dried on snot off little faces. My toddler calls them his "soft tissues" and will actually sit calmly while we gently wipe his face before bed and when he gets up in the morning.
I thought they were silly and would be a waste of money when we bought them - and they certainly are a luxury not a necessity - but we use them daily through cold season (which seems to last from November - April in our house), and they are very soft of raw little noses.
It's a little hard for me to believe I am recommending a special wipe for snot, but I am.
