One who washes his hands should not make Kiddush - הנוטל ידיו לא יקדש
Summary:
One who washes his hands should not make קידוש, either because it is a היסח הדעת, or he may be considered מגסי הרוח. One may wash his hands once in the morning and stipulate that it should last the entire day provided that water is (very) scarce, and he will make sure his hands do not become soiled or טמא.
