I have found that rinsing with water is quick and easy, but water has its risks. One, the cutters are made of steel and water can corrode them (rust or mineral deposits). Two, water could possibly leak into the electrical part of the shaver. A good brushing with an old toothbrush, plus occasional alcohol cleaning, and spray lubricant or light oil will preserve shavers. I find the foil shavers take more time to clean than rotary shavers, but they give a slightly closer shave.
