How do you delete cache steps?

when dealing with particle is there a way to delete the cache steps (i think they appear as little red lines in the Timeline) for all the particle systems in the scene?
As it is now, i would have to select each object that has a particle system, check, and then uncheck “Quick Cache”, then click the minus (-) button under the cache panel. That is the only way i have found to get rid of those little red lines.
I am working with about 20 different particle systems (a lot of times i work with more) so having to do this for every one of them after i hit alt + A gets a bit tedious. Sometimes they cause other issues, like in the case i am facing now, when i press alt + A blender locks up and i have to quit it.
