Good Afternoon All! I recently purchased a few Vintage Colgate Shaving Stick Containers to hold some of my Shaving sticks for travel. Although in decent condition, the finish is dull and shows some light surface rust. Any ideas on a safe and effective method to cleaning and restoring the shine? I haven't seen much information on processes for this. I was wondering if the process was similar to cleaning and polishing safety razors (which I have done before). I just don't know if all the products are safe to use on the containers (scrubbing bubbles, soap, water, maas polish). Any insight and advice is greatly appreciated!
