You should use a different command.  "clear ip route *" flushes the 
routing table out of memory, but the router will immediately re-apply 
any configured statics and quickly re-learn any dynamic routes.

 From global configuration mode, you will need to remove the static with 
the "no" command.  For example, if there exists a static route of the form:
   ip route 192.168.1.0 255.255.255.0 1.2.3.4

you would enter in global config mode:
   no ip route 192.168.1.0 255.255.255.0 1.2.3.4

The route will be withdrawn immediately.  No need to issue a clear 
command.  Don't forget to save your changes with a "write memory" when 
finished.

Note:  This is pretty basic stuff.  You may want to avail yourself of 
some of the Cisco network academy classes at your local community 
college if offered.
