Cleaning brass etc
I am restoring a Marconiphone T14A which has a brass speaker grille.This was absolutely filthy and tarnished. I tried all the usual cleaners, Brasso, etc. without any success. I "Googled", brass cleaner and came up with Quiksilver, on eBay. This plate, when used with soda crystals, boiling water and Persil non bio, should clean brass. I was sceptical, but decided to give it a try. Much to my surprise, it worked. When I dropped the grille into the solution, the plate seemed to effervesce and lo and behold clean, shiny brass. I haven't tried it on other metals, but is supposed also to clean silver, copper, gold, bronze and stainless steel. Does anyone know how or why this system seems to work?
