Removal of unwanted /home/user accounts

Is there a way to remove unwanted /home/user directories from a autofs Solaris 2.5.1 system? I can deacivate them by putting an * in the passwd file but I want to remove the directories and every thing in them. I assume it unmounting in some way the/home but have read it is treated “specially”. I am pretty new at this so be gentle :}
Thanks for all replies,
