Remove '- ' from page title

I want the page title on my search engine tabs to just be the page title. I have removed the site title through WordPress settings but am left with a ‘- ‘ after the page title. I have looked at removing this using the advice on this page

But the <?php bloginfo( ‘charset’ ); ? text you are advised to remove appears between <meta charset=”…………….” /> not between wp_title tags.

As this is in the Edit themes section I’m a little nervous. I’m assuming the difference us due to the Enfold theme. Am I ok to proceed or should I do something else.

Thanks as ever for your great support
