iptables -X
iptables -t nat -X
iptables -t mangle -X

man iptables, specifically the last line :

-X, --delete-chain
Delete  the  specified  user-defined chain.  There must be no
references to the chain.  If there are,              you must delete
or replace the referring rules before the chain can be deleted.  If
no  argument  is given, it will attempt to delete every non-builtin
chain in the table.
