If you have your own content that you would want to keep AND you have used the uninstall feature for all the modules that you have installed, then the only route is to manually check. if you don't have much content you could export it and replace the db with a clean one, then put your content back into it.

You can use the Schema module for discovering the remaining tables from not properly uninstalled modules.

You can also use DEVEL modules reinstall feature if you only want to clean the database but don't want remove the module.
