If you’ve placed some ruler guides and you simply want to hide them so you can not have to look at them now but you can bring them back later easily, then just got up to your view menu and then click on boundaries and guides so it doesn’t have the check mark and it will go ahead and hide them.

They’re are still there if you’d like to get them back go ahead and go to view again and then click on boundaries and guides and I’ll go ahead and show up again. Now you can remove a ruler guide simply by selecting it and then go in ahead and dragging it back up to its ruler and release in it and it will delete it.

However, if you have several ruler guides and you’d like to remove them all at once then go ahead and go up to the arrange menu. Go to ruler guides and then click on clear all ruler guides and it will go ahead and it will remove all the ruler guides that you have displayed in your publisher document.
