Database Cleaner: Clean, Optimize & Repair


With a ton of features and the ability to handle even the largest of databases, Database Cleaner is built on years of experience with the other related plugins and the latest versions of WP and PHP. Thanks to its user-friendly interface, you’ll be able to easily navigate everything and make sure everything is just right. Plus, if you have a lot of work to be done, Database Cleaner uses asynchronous requests to tackle it slowly and steadily, helping to avoid errors and timeouts. You’ll find more information here: Database Cleaner.

IMPORTANT: Always create a backup of your data before using such a plugin! It works well, but better be safe than sorry! 🙂


  • Easy and Expert modes.
  • Auto Clean button. Choose the items you’d like to clean automatically, and let the plugin do the job!
  • Keep statistics and historical data about your database size.
  • Allow you to browse your data to better understand it and to categorize it.
  • Handle oversized databases through asynchronous and decently sized requests.
  • User-friendly UI, solidly built, that will evolve with time.

What does it clean?

The usual, which are: Revisions, Auto-Drafts, Deleted Posts, Orphaned Post Meta, Orphaned Term Meta, Orphaned Term Relationships, oEmbed Caches, Unused Terms, Duplicated Term Meta, Duplicated Post Meta, Orphaned User Meta, Duplicated User Meta, Unapproved Comments, Spammed Comments, Deleted Comments, Orphaned Comments Data, Duplicated Comments Data, Expired, Transients, All Transients.

Database Cleaner also gives you specific tools to analyze and check how your data is used for:

  • Post Types
  • Tables
  • Options
  • Cron Jobs

Database Cleaner use its own references and analysis to figure out by which plugins or themes your data is used. An even better support of this feature is supported in the Pro Version.

Why this plugin?

There are other database cleaners. I used them, but I always found them were imperfect, with old UI, too many missing (or half-cooked) features, limited ways to look into the data. The worse for me is that none of them can actually can handle big databases! Based on all those issues, I craft my own, and here is the result. And now, I am working hard to make it the best for all of you, and for all kinds of WordPress and databases.

Any feedback? I am here 🙂 I would love to talk with you and make Database Cleaner better for you.

I am not a WP professional, but I have an educational website that recently got attacked by virus. After installed this plugin, the page got recovered. That was magical 😉

I've just started to use this plugin for all it's worth. I knew that WordPress databases get bloated over time as plugins and themes are installed and eventually uninstalled, but boy was I surprised to find more than 1,500 autoloaded options on a website I manage, which has been in existence for well over 5 years! I have used free database cleaners before, but this one is the best from what I can see. The interface is clean and straight-forward, and the actions don't hang on a large database either (unlike some plugins I've used). The Pro version includes the ability to see hints about which plugins the data in the database is coming from, which is pretty accurate (accurate enough to be helpful), and will doubtlessly become more accurate over time. I highly suggest purchasing the Pro version if you're website is more than two years old and you have enough experience to work with WordPress database data. Thanks Jordy for a great plugin! You deserve to be much more well-known! I hope this review helps a little in that regard. P.S. As mentioned in several places, including in the plugin itself, always make a backup of your website before making changes to your database with this, or any plugin like it.

I was concerned about this plugin and ran several tests in which it seemed to have not recognized several graphics that were actually attached. So I backed up the uploads directory to an external drive and ran it. I was amazed. I have not been able to locate any missing graphic. I cannot recall how many MEGs of graphics it removed but it was substantial. This is the best database cleaner I have found. Thanks Jordy!

Dear creator of the WordPress database maintenance plugin, I am writing to express my sincere gratitude for your amazing work in developing this plugin. I am completely amazed at how well-built it is and how easy it has been for me to use. Thank you for your dedication and for putting so much effort into making sure the plugin runs optimally. Your attention to detail and passion for quality are evident in every aspect of the plugin and have saved me so much time and effort in maintaining my database. I wish I could give you the recognition you deserve for all the work you've put into this plugin. You are a true professional and I am deeply grateful for your generosity in sharing it with other WordPress users. Warm regards and thank you again for all your hard work. Sincerely, JUAN LUIS MARTEL

I've been using Meow Gallery and Meow Lightroom for a good while. Last year I started using Meow Media Cleaner and I have just renewed my license. Meow Media Cleaner is a great tool for cleaning out legacy images from the WordPress Media Library and a great companion to Meow Database Cleaner. This year I opted to try out Meow Database Cleaner (Pro). It follows the same guidelines of the other Meow products I have been very happy with. It is powerful and presented in both a simple version and an advanced version. Like Meow Media Cleaner take note of the Health Warning. Back up before you use in case you need to roll-back. My recommendation is that you take multiple-back ups! is our hobby blog. It's about 8 years old. Over that time we've used a few themes, we used to used NextGen Gallery, we've used multiple contact forms... - in fact there was load of legacy crud in the database after 8 years! Meow Database Cleaner has allowed me to clean up a lot of the legacy crud, cleaning up the PostTypes, removing lots of legacy Tables, cleaning up the cron jobs and cleaning up the Options. The latter is where a huge amount of work was done. The data here is dived into: Not Used, Used and Unknown. After lots of interrogation, that allows you to look at each record, I've been left with Not Used (10), Used (529) Autoloaded (486) and Unknown (67). Unknows started off at nearly 500! For the Not Used and Unknown after looking at the records, I am left with stuff I cannot that I cannot link to a legacy theme or app. As I have no way of knowing what these unknowns are linked to my mantra has been "if you cannot deduce what the record is linked to keep it" With Meow Database Cleaner I have been given the tools to help me clean up 8 years of legacy crud that I was previously scared to do. I cannot emphasise how important it is to heed the warning on the packaging. TAKE MULTIPLE BACK-UPS. You can really screw up your site if you clean / delete the wrong thing. Let me share my experience. My first go was a failure - I deleted too much and lost all my Tablepress tables - and had to do a roll back. My host is SiteGround and they give you the tools to take manual back-ups. After I did the roll-back I thought I had really screwed up. What I forgot to do having rolled-back was to manually clear the SiteGround cache. Once I did that, PHEW, the roll-back put me back to my pre Meow Database Cleaner condition and I could re-start. My second attempt was very successful as I was much much more diligent with the cleaning and cross checking. This is why having back-ups is so so important. My second go has taken hours of work cross-checking with interim back-ups I'm very happy with the Meow's new database cleaner. Jordy and the Meow dev team really want to make this a great database cleaning tool. I also urge you to share your feedback with the Jordy et al. Well done team Meow.
