There is perhaps no better way to fake texture than to add color gradations. Then add enough vinegar to the ziploc to cover the surface you wish to soak (about 1/2 cup). Soak for a couple of hours, take the plastic bag off and then run the water. Mildew and soap scum can not only block a shower head but also ruin the finish on a fastener, either metal or plastic.
