An ultrasonic bath maybe?
While I agree with Buster's recommendations in general, I need to say that:
1) Don't boil a gold-plated or plastic/resin razor. Boiling a gold razor removes the protective lacquer on gold plating and may discolor and/or melt plastic or resin.
2) Don't use any kind of polish on a silver-plated razor, use the aluminum foil and baking soda method described elsewhere on B&B.
2) If you have any painted or plastic surfaces on your razor, CLR, boiling, and even a major soak with Scrubbing Bubbles might remove or damage these surfaces. SB is the least damaging and should be OK for such things as adjustable dial numbers etc. but even there, go slow, check regularly, and rememeber: it's always easier to try it again than to ruin something forever!
Got a new vintage razor and noticed the TTO feels "backed up" TTO functions smooth, but I think it's due to residue, doesn't feel clear. What are the best, yet safest way to clean it?
Barbicide is used as a disinfectant, and that's all it does.I also find Barbicide will help cut through gunk as well, and is meant to soak razors and other kinds of cutting tools in.
Are you sure its not designed to be that way? TTOs will give some resistance during the last quarter-turn when closing. This ensures that it is not just closed, but locked.Got a new vintage razor and noticed the TTO feels "backed up" TTO functions smooth, but I think it's due to residue, doesn't feel clear.
