Remove Sub intro post text throughout site

Hi

I managed to get rid of the Sub Intro post text on the home page, and the background to it, by deleting the whole first section from the sections.php file, but can't get rid of it on the inside pages. I don't want it anywhere, it doesn't display properly when I try to add text to it, and the fact that you can't delete it is just annoying!

Please advise.

Thanks
