I bought a box of old razors for $ 6.00 dollars ( $ 1.00 each ) at a Church Rummage Sale ( photo attached ), and wanted to know how to correctly clean the razors without damaging them. I just gave them a basic clean with hand soap, but thinking about using an ultrasonic cleaner. Do you think that the Gold paint will come off the Gold two gold razors ? I don't plan to shave with these, just maybe use them for an Art project, but don't want to destroy the finish of them. Thanks for your help.
