all of the alcohol based cleaners will smell/taste poor until after they evaporate. Something like purell should work fine (doesn’t leave a residue) but will smell somewhat strong until it evaporates…
You could try using this and then afterwards maybe some hand cream?

Honestly there is not a real need to keep your baby’s skin that clean. Studies have shown that baby’s raised from a young age in day cares have the strongest immune systems and have decreased risks of some diseases including leukemia. All of our skin is covered with billions of bacteria naturally. Killing of the non-harmful bacteria actually make it easier for harmful bacteria to gain a foot hold and cause disease. A regular washing at home for about 15 to 20 seconds will get his hands sufficiently clean. Isopropyl alcohol can dry out the natural oils of the skin, of which babies do not have enough of in the first place.
