    I got a VCR that was in a house fire, and it's video drum has smoke
    damage.

    It doesn't feel smooth, but isn't rough enough to where it seems to be
    damaging tapes. Matter of fact, it records and plays just fine.

    But I want to clean the drum. How can I clean it?

    Here is the condition of the drum: http://img.photobucket.com/albums/v395/Evilweredragon/tapehead.jpg

    It's been a long time since I've worked on a VCR, but I use strips of clean
    white paper dipped in alcohol. Press firmly against the drum and rotate,
    being careful to hold the paper still so you don't break the head chips.
    Repeat with new paper until they quit getting dirty.

    I've tried to clean it, but nothing is coming off.. Not even the
    slightest bit.

    It's as if it's caked on there pretty good.,

    I've found kitchen oven-cleaner very effective at removing heavy tobacco
    smoke staining from parts.
    Go sparingly, squirt onto copier-paper, and then use that on a test area
    first, below the tape path and don't use near the tape-heads as it may be
    too corrosive on the winding enamel etc, no need as by your account not
    affected there anyway. Remove any remainder with some meths or alcohol,
    again soaked into paper.
    No cotton buds/balls at any stage, chamois is ok.

    If Xylene won't take it off, it doesn't need to come off. Xylene was
    the official recommended head cleaner of Ampex on their commercial
    VTRs. Texwipes or the chamois swabs do well. Ampex specifically warned
    of alcohol as it leaves a "persistent film". I tought it was silly
    until I cleaned a machine with Xylene and saw to power to spin the
    drum drop by a factor of 10. Now I'm convinced.
