First I scrub my vintage Gillette’s with Dawn and this Polident denture Brush. I found that it’s bristles are a lot stiffer . It also has another side to get inside the nooks and crannies . Then I use FLITZ POLISH to shine it all up. Next I put it in the dishwasher After that I use TESTORS BLACK SEMI GLOSS ENAMEL PAINT. For the numbers . I use this paintbrush so I only get the amount I need
