I'm curious for the best ways people have found for removing white build-up I've found on razors, grooves in brush handles, etc. It looks most like some old dried up shaving soap leftovers or so, perhaps from imperfect rinsing after use of the years. I've tried rinsing under high pressure, hot water and, when not near a blade, scratching a bit with my fingers without much luck.
Thanks!
Thanks!
