Completely removing sideboxes from the Admin panel

Hi.

I have a load of sideboxes switched off in the Admin panel which I want to completely delete from the site.

I have tried the obvious of removing the sideboxes from the current template but it is still showing.

Please could somebody advise how I remove all traces of them?

Thanks in advance

Sideboxes have roots in languages, modules and templates and also in the template_default all traceable with a search for the sidebox name in your fileset.

Did you manage to remove any sidebox traces?
