I read in the "Cleaning and restoring" article that you don't use Brasso. Why?
I use it all the time and it works fine.
Only when chrome is fading and brass shining through or chrome hasn't been applied verry well and brass is bare, the chrome dissapears when using it, but I think this will happen with any metal polish.
Besides: how does it come that chrome doesn't goes off during cleanig when it is applied all over a surface and does goes off around spots where brass is visible and so making the spots becoming larger?
