The washing mitt, made of naturally anti-bacterial JungleVine®, is abrasive yet safe for scrubbing any of the stuck-on grunge you encounter. It will not scratch surfaces. One side is a fine weave and the other side is a coarser weave. These mitts are great for removing soap scum and hard-water buildup in the bathroom. You'll want one for the kitchen, too, for scrubbing the sink, stove top, and oven.
