How to remove a specific iptables rule?

Question

linux

Hello! Blocked port 80 by issuing commands

iptables -A INPUT -i eth0 -p udp -m udp --dport 80 -j DROP

and

iptables -A INPUT -i eth0 -p tcp -m udp --dport 80 -j DROP

now we need to remove these two rules, but besides these rules, there are many more, and I would not like to re-enter all the rules with the iptables -F command.

Thanks, all methods are good. But as Mystray said, it's more convenient, IMHO.
