Or TP for the initial cleanup. Water to finish it off.
And if you're not in public restrooms: use your hand with the water for a deeper clean, and then walk to the sink to wash the hand with soap.
Much more hygienic than just TP.
I think it should be the other way round (ie. more optimal with water first).
Water and TP? You don't know how to use the three seashells?
Hahahaha this was the first thing I thought of too!
One of the greatest mysteries of the universe right there.
Clearly you don't either otherwise you'd know that's what the first two are and you're just grandstanding.
