All that I have read about video equipment recommends that either
the heads simply not be cleaned or at most cleaned by the alcohol
and swab method.  All the advice I have read definitely indicated
that the head cleaner cassettes where not recommended, in fact,
more likely harmful.  There is good reason that video heads are
less likely to need cleaning than audio cassette heads.  The audio
tape players heads actually have a small gap which a field is
applied or detected which can become jammed with shedding oxide.
The video players have no such gap (or maybe the gap is filled
by a non-magnetic material, I can't remember).  Thus, the heads
are much more resistant to picking up garbage and need much
more infrequent cleaning.
