How do I remove Dynamic Vlans on a Powerconnect 6224

Greetings all

I have recently started at a new site and am in the process of cleaning up the network. I have a Dell Powerconnect 6224 that has 4 dynamic vlans that need to be removed, can anyone point me in the right direction.

I know to remove static vlans is going to "vlan database" and then "no vlan id"
