I like this Waterfall Soap Saver's simple idea for making my Zest last longer, and also for preventing it from getting that slimy Gulf of Mexico catfish skin it always acquires when left to sit in its own wet glycerin-ness. Pretty handy. My mama points out you could also install the Soap Saver at your kitchen sink to help drain the wet funk out of dish sponges. No more slithery, mushy soap and no more bacteria-infested, reeking sponges "cleaning" your dirty plates and utensils.
Waterfall Soap Savers are made of plastic and have 2 built-in prongs to hold soap, or whatever else you need to store on a decline, in place.
