A housekeeper once bent the cantilever on a Grado Reference cartridge. I sent it to Grado who straightened it out for free. When I called to ask about the cartridge, I spoke to Joe himself. He said I still had many hours on the stylus. Before we hung up he said, "Don't put any more gunk on the stylus. It took me a lot of time to get off. These diamond needles are so hard that dust can;t really stick to them. A brush is fine."
From then on, I have never used "gunk" to clean my stylus. I have a short bristled brush and a long bristled brush. That's it. Gunk be gone.
