Steel bristles cut into that surface and break the growth loose so the sanitizer and the filter can finish the job. The metal back keeps the brush from flexing away from the wall while you lean on it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOne important limit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe bristles are metal.
