Last night while looking in a box I saw the bag of mice I keep handy and decided to clean the rollers. Some I’d done before but a fair number I hadn’t. All went all except a couple of Japanese M0100. The gunk really stuck to the steel rollers. I scraped the thick stuff off but I’m not the happiest with the result. Looks like a bit of corrosion and still some black stuff on the rollers. Probably wouldn’t be hard to clean up better if I could pull the rollers but I’ve never tried with this mouse and a bit worried about destroying it
