Markd51 - Good description of "safe" scrubbing (which I didn't describe). Also, I completely agree that a pre-cleaning dust-off of some kind is fully appropriate, and do so with and old VPI record brush (and usually a few Zerostat zaps to deal with the static).
It's a darn nutty ritual, isn't it? But feels somewhat virtuous.
