What are WordPress trash posts and how to clean them?

A trash post is a post that you have deleted from your WordPress site and have been moved to the trash. A trash post is not visible in your site and should be deleted since it is not used.

You can either use our plugin Advanced Database Cleaner to clean-up these trash posts or execute the following SQL code (which is used by the plugin) directly via your phpMyAdmin:

DELETE FROM posts WHERE post_status = 'trash'
