cleanRAM has a scheduler that you can set to your liking...
how deep a cleaning you want to perform, days of the week, time of the day.
I'm finding a deep cleaning (lvl 3) once a week and a level two every so often...helps things tremendously.
there is also a custom cleaning where you tell the cleanRAM what programs to "clean"
