Well. Haha, its kind of strange. My first obvious guess would be that you're obssessed with cleaning? Hah! If not, perhaps there is something specific plaguing your subconscience? The fact that you keep searching out new ideas on how to clean them makes me believe you're just trying to come up with a solution to something.

This is a stab in the dark though. Wonder if you are an extremely tidy person by any chance?
