If you're looking to clean up your WordPress website and remove unnecessary objects, there are a few steps you can take to achieve this. First, it's important to identify the objects that you want to remove. These could be unused themes, plugins, images, or any other files that are no longer needed. Once you've identified the objects you want to remove, you can follow these steps to clean up your WordPress site.

1. Remove Unused Themes: Go to the 'Appearance' > 'Themes' section in your WordPress dashboard. Here, you can delete any themes that you are not using. Removing unused themes can help improve the performance of your website and reduce the risk of security vulnerabilities.
