Use SprayAway glass cleaner, it is a water based cleaner and will not dissolve the silk-screening on the faceplate. Apply with a toothbrush and wipe off with a cotton towel or diaper. Depending on how dirty it is, you might have to apply and remove several times.
Cleaning vintage integrated amplifier
Looking for some advice on cleaning my Denon PMA-757. I finally got it connected to my second system and it sounds fantastic. However, I'd like to clean the silver faceplate a bit. Over the years, it's turned from a champagne/silver color to an antique gold color. Any suggesting of cleaning products to get her shiny again? Thanks so much!
