Though I do this once every year or so, I use Record Research (now Mobile Fidelity) Deep Cleaner on a new and dampened sponge to lightly clean the surface of the platter. I figured the same solution that is OK for records would be OK for the platter as well. Then I repeat with the Super Wash.
Cleaning VPI platter
Is it safe to use a glass cleaner to clean the acrylic platter on a VPI scoutmaster? Is there a better way? Mine just got a lot of smudges from curious hands. Thanks.
