Cleanup 
Remove the whole setup or the only the selected chains, without baking. so it reverts back to be like before.
Target / Selection Filter
Use selection filter to clean all the temp ctrl chains, or only the selected, or relative ctrl rig (in case of multiple control rigs).
Note
When using selected to remove a chain, it's enough to select only one bone from the chain. It's not necessery to select all the chain bones.
Clean
Constraints
Removes the constraint from the original bones
Ctrls
Removes the Temp Ctrls. If there are no ctrls left, then the rig will be removed completly.
Rebake Link Ctrls to Original
When Using multiple chains that are linked with each other, sometimes when removing a chain with cleanup, it can break the hierarchy, and therefore the animation would break as well.
In this case Temp Ctrls will Re-Bake the animation to avoid breaking it.
The user can decide if everything rebakes to the original animation or the current temp ctrls setup
