Cleaning Question Re: Brass Plates
Good evening.

Cleaning question....

I clean my watches manually (jars and brush) using L&R cleaner and rinse. The watches end up being clean, but with brass(?) plates, they still have that orangeish color. I had an old plate from another watch and tried some Silvo metal polish on it and WOW Cool what a difference. Nice and shiny! Has anyone used this cleaner or a similar polish cleaner before? Are there any negative side effects? I would clean the plates first with the metal polish and then with the L&R to make sure that all the excess residue from the polish is removed. Any comments? Ideas? Warnings…..

Thank you!

I beleive what you are refering to as brass might actually be gold guilded plates. A very fine layer over the base metal, which can be brass. Any polishing can easily remove this guilt which would severely diminish the value of the watch. For gold guilt movements I have used L&R #111 which is an ammoniated cleaning solution. This leaves the plates sparkling like they should
