If you installed a fresh WordPress blog system on your website before writing new posts, you will need to remove the sample comments, blog posts, etc. This can be done in the following way:

1. Login to your WordPress admin dashboard.

2. Under the Dashboard menu, hover your mouse on Posts and click on All Posts.

   

3. Hover your mouse on the Hello World post and the Trash option will appear. Click it to remove the post.

   

4. Now do the same with the sample page by pointing your mouse on Pages in the dashboard menu and then choosing All Pages.

   

5. Choose Comments from the dashboard and then the Trash option will appear. Now click it.

   

After you take these steps, your blog will be clean, without sample posts and comments and you can start blogging.
