It has been my experience that once you start cleaning a rotary head
with qtips and alcohol the head is gone. If the '"dirty up" brush, then
a cleaning tape, won't clear things the head is gone. It is not
cost-effective to replace. You can buy an SSD based recorder/player for
way less than the cost of a new drum.
