I also agree about the Griots Garage Best of Show Wax, I use it on my classic cars, and my audio equipment, turntables and speakers, and the finish is superb.
Am I out of my mind? #obsessed
I have a pair of B&W 805d3 stand mount speakers. I dust them weekly with a microfiber cloth. From a few feet away they still look brand new but on closer examination they aren’t perfect. Tiny micro scratches and smudges. I had the thought of trying a polishing product or car wax to make them perfect again. Good idea or am I just #obsessed?
