Tap water? Why not distilled water? Why not pure grain alcohol? (197 proof ethanol)
Water's all fine and dandy, but tap water? Surely you keep distilled water on-hand to block Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.
For me, the cleaner of choice is pure grain alcohol and a toothbrush. It will absorb the remaining water and whisk it away.
