I prefer self-healing also. FYI... I clean mine with a couple drops of dish soap and a finger nail brush. Then Rinse it in the shower with the hand hold spray thing. Then I let it dry on the kitchen counter with a towel under it. I do not scrub hard. Just work up a little foam with a little water in a spray bottle or dip the brush in a bowl of water from time to time. Baby Shampoo works great too.
