Instance Question

What is the best way- if there is a way, of course- to delete the multi-colored lines from view?

Is there a better way than searching for each one on the Scene Tab, to remove them, one at a time? 

(...which doesn't always work, because I cannot always find a node that will remove one.)

I know that they don't show up in a render, but I would also like to be able to clear my main viewport of them, if possible.
