Estracell Wedge Edge is a multi-surface scrub sponge with a patent pending shape that reaches deeper into hard-to-get-to corners and crevices. The multi-surface scrub material is designed to clean most surfaces. Great for removing build-up in hard to reach places on the stove, around the sink, bathroom and all around the home. The Estracell Sponge side reaches in and easily wipes up and rinses dirt and food particles down the drain. It can also be used on non-stick grill tops. Independent test results demonstrate that bacteria will not feed and survive on the sponge fibers of Estracell sponge material…Naturally. Also, the unique cell structure rinses cleaner and dries out faster, eliminating the perfect breeding condition for bacteria and fungal growth. These qualities make Estracell…More Sanitary.
