You might try Audacity audio editor: http://audacity.sourceforge.net/
Otherwise you're at the mercy of the tape deck you're using.
Some reel to reel decks had a noise suppressor circuit onboard that would cut the upper frequencies where hiss lives. But they also cut off your top end.
If using cassette tape, try turning on the dolby noise reduction, if available.

Audacity can remove some noise but it needs to be able to sample the noise you're incurring. This is best done by recording a few extra seconds of silence before or after your recording. You can always trim the extra silence from your file afterwards.
Hope this is helpful.

Acoustica can do the same thing (but costs money after the free trial expires). Did a reasonable job on my tapes (which came from vinyl). 'Depopper' (Google for it) does a good job on clicks, pops, hisses, 50Hz hum, etc. but runs very long times.

Then you have to chop it back up into tracks and albums .. I used Acoustica again (or Polderbits).
