I've had the battery-powered vibrating brush for almost 20 years. Just changed the battery for the first time!!!

The only other thing that touches my stylus (NO FLUIDS!) is Silly Putty. Yes, seriously.
My boss from the first hifi shop I ever worked in had done a lot of experimenting with old styli that were traded in by customers - doing all kinds of crazy things to them and then examining them under the microscope (it was a requirement to have one back in the day - we're talking about 25 years ago). One day on the bench, he had a woofer that had been melted by some hammerhead. The rubber surround had become a goopy mess. Just for fun he took a dead cart and stuck the stylus in the sticky goop. He then stuck it under the microscope, expecting to see some black, tarry yuckum.

Instead he saw a clean, shining, stylus that looked cleaner than he was used to seeing new styli.

I don't remember how this stepped from melted speaker surround glop to Silly-Putty, but everybody whose been through that shop has been using this method for years, and while it's always seemed like a logical chance, nobody has yet had a stylus ripped from the cantilever by doing this.
