HaLeiVi: To use a whole Revi’is is just an Eitzah Tovah because it avoids a lot of problems. As long as you begin with a Revi’is, you can use as little water as possible so long as you get water on every part of both hands.
The wipes wouldn’t work because you need the water to come from a Revi’is gathered in one place. The water doesn’t have to be drinkable but there are limits (this has its own Siman in the Shulchan Aruch, somewhere around 158 I think).
