WordPress is no doubt a memory hogging blogging platform but by the end it’s the best blogging platform. There are thousands of plugins which will help you to do anything with your WordPress blog.
One thing which WordPress need in regular basis is optimization. This could be optimization of your WordPress theme or database. Whenever we install a plugin, it adds tables into database and when we disable and uninstall plugin, it doesn’t mean those tables are deleted.
To uninstall a WordPress plugin completely, you should also delete those options created by plugin.
Clean options WordPress plugin is one such plugin which help you to find all orphaned options from your database and help you to delete them completely. Though before you read further and install this plugin, I highly recommend you to take a backup of your WordPress database.
