The lazy method: add 20% misfuel, leave for 24 hours, pour clean fuel off top into tank 
Everyone has their own method, but it usually consists of some sort of heating, settling, draining the crud off and then final filtering (usually to 1 or 5 micron). No need to "filter loads of times", gravity is your friend, all of the water and heavy fats wll seperate to the bottom of the container given time. If you can get some misfuel it will greatly reduce your work, accelerate seperation and improve the quality and yield of your fuel.
