Yes, you do indeed need to clean the heads on these machines periodically. Alcohol is the cleaning solution. Use only very pure alcohol. Denatured from the hardware store or 80 percent plus from the phamacy.
The heads also need to be "degaussed" from time to time. YOu need a special device for this and need to get all your tapers out of the room or else the degausser will damage them with the intense magnetic field it created.
However the dropouts you are experiencing are more a problem of the tape. This is common with tape that has been previously recorded - recording over, in other words. But you say it is new tape.
It may not be brand new at all. It may be "new - old stock", and has been sitting around for a decade. Tape doesn't last forever and some formulations even get gummy over time. It may simply be a cheap brand of tape.
