Transient Cleaner is a WordPress plugin designed to help users manage and clean expired transients from their options table efficiently. It offers manual transient cleaning for all WordPress versions, even those prior to version 5.8, enhancing the functionality of WordPress's core features. The plugin ensures compliance with WordPress and VIP coding standards, making it a reliable choice for site administrators. Users can benefit from a cleaner database by simply activating the plugin, which also includes recommendations for clearing transients after database upgrades.

The plugin features an options screen under Administration -> Tools -> Transients, allowing users to customize cleaning schedules and perform ad-hoc runs. For those prioritizing performance, a lite mode can be activated, which hides the options screen and uses default settings. Additionally, developers can utilize provided hooks to integrate cleaning functions into their own code. Overall, Transient Cleaner is a valuable utility for maintaining an optimized WordPress database.
