<h4>Why use this plugin?</h4>
<p>Over time, WordPress sites accumulate post meta data from plugins, themes, and page builders. When you switch or remove plugins, their meta often stays in the database — bloating tables, slowing queries, and making backups larger. Post Meta Editor and Cleaner gives you direct control over this data.</p>
<h4>Key benefits</h4>
<ul>
<li><strong>Database optimization</strong> — Remove orphaned meta from deleted plugins to reduce database size and improve performance.</li>
<li><strong>Source identification</strong> — See which plugin or theme created each meta key. The built-in source map recognizes 50+ popular plugins (WooCommerce, Yoast, Rank Math, Elementor, Jetpack, WPML, and many more).</li>
<li><strong>Bulk delete</strong> — Delete more meta keys at once. Adjust process speed to avoid timeouts on large sites.</li>
<li><strong>Search and replace</strong> — Update URLs, domain names, or text across all posts. Works with serialized data (arrays, objects) — both values and keys can be updated.</li>
<li><strong>Flexible deletion</strong> — Delete the entire meta key and its values, or clear values only while keeping the key structure.</li>
<li><strong>Safe editing</strong> — Overwrite meta values in bulk, or perform targeted search-and-replace. Ideal for migrations, domain changes, or fixing incorrect product data.</li>
</ul>
<h4>What you can do</h4>
<ul>
<li>Clean up after removing plugins or themes.</li>
<li>Migrate a site and update old URLs in meta fields.</li>
<li>Fix WooCommerce product attributes, SEO meta, or custom fields in bulk.</li>
<li>Identify and remove unused or duplicate meta keys.</li>
<li>Reduce <code>wp_postmeta</code> table size for faster backups and queries.</li>
</ul>
<h4>Important</h4>
<p>Before making any changes, create a backup, as modifications and deletions can only be restored from a backup.</p>

<p>There are times when your database gets filled up with duplicate entries that you may not want.  Cleanup Duplicate Meta allows you to check for any duplicates in either the Post Meta or User Meta tables.  Then if you want to get rid of them, simply click on the Cleanup button and Cleanup Duplicate Meta deletes the duplicates leaving either the first or last meta (you select which).</p>
<p>The interface is simple and easy to use:</p>
<ol>
<li>‘Check for Duplicates’ queries the database and then displays all the duplicates found.</li>
<li>‘Count Duplicates’ counts all the duplicates found in the database (i.e. a total count).</li>
<li>The ‘Cleanup’ buttons trigger a SQL query to run, which deletes each of the duplicate entries, leaving either the first or last one (per your selection) in the database.  All non-duplicates remain untouched by the plugin.</li>
</ol>

Cleanup Duplicate Meta

I was just about to write up my own plugin as a soltuion to clearing duplicates when I can across this plugin.
Cleanup Duplicate Meta is an awesome plugin that just saved me a good deal of time. Within a few minutes of installing the plugin I had successfully purged around 3,200 duplicate entries from a clients database (after taking a backup ;]).
Thanks for putting this plugin up in the repo for others to take advantage of!

Cleaned up nearly 70,000 redundant _postmeta records with just a couple of clicks. Top marks.
