I am unsure about using Pledge on audio equipment. I recall standard advice used to be not to use any cleaners containing silicone near audio systems. A thin film of the cleaner remains after wiping off the product and the silicone content apparently migrates slowly from the site of application and eventually coats electrical contacts. Whilst not causing a failure but resulting in a less than optimal connection, it's one cause of that "I am sure that it doesn't sound as good as it used to" feeling.
The OP should try to obtain proper anti-static foam cleanser made for cleaning the exterior of electrical products. In the UK that is Servisol Foam Cleaner 30 obtainable form Maplins (our equivilent of Radio Shack). I do not know what the US counterpart is but I am sure that there will be one.
