Back up before deleting data
Open OptiWave → Database. Cleanup categories are off by default, and automatic cleanup is disabled. Review the counts and make a database backup before running a cleanup.
Choose what to clean
| Category | What it removes or changes |
|---|---|
| Revisions | Previous saved versions of posts. You lose the ability to restore those versions. |
| Auto Drafts | Automatically created draft records; review ongoing editorial work first. |
| Trashed Posts | Posts already in the trash, permanently. |
| Spam Comments | Comments marked as spam, permanently. |
| Trashed Comments | Comments already in the trash, permanently. |
| Expired Transients | Temporary stored values whose expiry has passed. |
| All Transients | Temporary values, including unexpired ones. Plugins may need to rebuild them. |
| Optimize Tables | Asks the database to optimize supported tables; behavior depends on its engine. |
Run a manual cleanup first
Select only the categories you have reviewed, let the settings save, and choose Optimize Database Now. Start with expired transients rather than clearing all temporary values unnecessarily.
Check the result, then visit important pages and open the editor. Deleting old data can reclaim space; it does not guarantee faster queries on every site.
Schedule only the cleanup you need
Schedule Frequency offers Disabled, Daily, Weekly, or Monthly. The saved cleanup categories are used for scheduled work, so review them before enabling a schedule.
Use a quieter period for larger cleanups, maintain regular backups, and make sure WordPress cron runs reliably. Leave the schedule disabled if you prefer to review each cleanup manually.
