If I may ask.....in what capacity are you wanting to clean and reuse the oil? At Home? In the restaurant? If the oil is old oil from the resturant you work at and has been discarded is that what you are thinking if using? Personally I'd think twice. It can be contaminated or cause you issues in your home. It's best use at that point is bio-diesel.
It's been my experience that people store the oil in most home fryers for 3-4 uses or until it looks too dark. You can always let it cool and strain it through a coffee filter or cheese cloth. I'm not sure if they sell filter paper for the home but it may be worth checking into if you like.
As far as for a restaurant, in my kitchens we filtered oil nightly (sometimes after lunch shift too) and rotated oil from one fryer to the next and so on only adding new oil to one fryer and completely emptying old oil twice a week from another. The oil that was discarded was not suitable for any type of consumption.
