E-Cloth is hand-wash only, but at least it doesn't get sour

Hand-wash only — but at least it doesn’t get sour.

E-Cloth explicitly says no to the washing machine. You have to hand-wash it. The consolation prize: it dries fast and doesn’t develop that funky sour smell that most microfiber gets when it stays damp too long. So you’re stuck with sink duty, but at least the cloth stays fresh between washes.
