delete all rules from iptables

Question

I'm make a shell script have some rules to limit connection on port Then it's effect badly on my vps

Script :

#!/bin/bash
# Window of time in seconds
SECS=60
# Max connections per IP
MAXCONN=5
iptables -A INPUT -p tcp --syn --dport 5222 -m state --state NEW -m recent --set
iptables -A INPUT -p tcp --syn --dport 5222 -m state --state NEW -m recent --update --seconds ${SECS} --hitcount ${MAXCONN} -j REJECT
iptables -A INPUT -p tcp --syn --dport 5223 -m state --state NEW -m recent --set
iptables -A INPUT -p tcp --syn --dport 5223 -m state --state NEW -m recent --update --seconds ${SECS} --hitcount ${MAXCONN} -j REJECT
iptables -A INPUT -p tcp --syn --dport 5224 -m state --state NEW -m recent --set
iptables -A INPUT -p tcp --syn --dport 5224 -m state --state NEW -m recent --update --seconds ${SECS} --hitcount ${MAXCONN} -j REJECT

And I need to remove all this rules

How can I do this?
