Hey I just wanted to hear some of your opinions. I don't really use DE razors, I rather my straight; but I fell across a fatboy at a garage sale for a lot less than it's worth so I had to buy it. I tried cleaning it with a toothbrush but I can't seem to get in all the little holes. My dad's a jeweler and has access to an ultrasonic bath. Has anyone ever used one to clear their razors? if yes, would it remove the paint in the numbers?
