I can't seem to get the fine ceramic rods on my sharpmaker clean anymore, despite using a variety of methods (comet/toothbrush, rubber eraser, soap and water) it keeps a metallic film and lacks the fine grinding sensation it used to have. Do these rods wear out fast? I don't know how many hours I've put on them but it hasn't been excessive in my mind.
Any cleaning or renewal or product life advice would be appreciated.
Thanks in advance.
