Don't bother. SQL queries will give you the answers, but you won't be deleting with SQL (unless you want to end up with a totally broken Jira)
I would check over your list of projects and delete or reconfigure any that need it, so they use the shared schemes as much as possible.
Then go into each list of schemes (workflow schemes, field configuration schemes, issue type screen schemes, etc) and look at the bottom of the list. There is an "inactive" section - expand it and delete all the items in there. Then do the same for the baseline configs (workflows, screens etc). You might find it best to repeat this a couple of times.
