Head Cleaner

Am I referring to fixing my camera or my country with a new "head cleaner"?  Could that be a synonym for the new President?

Anyhoo, I just got one of these (the Panasonic brand, not the Presidential kind) in hopes of a healed MiniDV camera.  It started acting up last fall, but I've recently discovered that these head cleaner cassettes may be the only troubleshooting necessary.

For whether or not this works, though, I'll hafta get back to ya!
