You should think about purchasing a pair of gloves. They leave your saber clean as new. You'll probably end up bringing out your saber more often because you don't have to worry about the long cleaning process. Grease and finger prints are a killer to get off.
I've had my Anakin ROTS for about 3 weeks now and to be honest I've only ever touched it with my bare hands once, which was when I first took it out of the box the day I received it. After taking the time to clean it that night I figured it's gonna be a hassle doing this process everytime, so I went out and purchased some thin cotton gloves. In my opinion, don't get these because the heat from your hands transfer through the cotton and onto the hilt leaving it it quite wet. But hey, no grease or finger prints :). I recently bought some soft leather gloves and these are great. They're a bit thicker than the cotton gloves though so I can't really feel the lightsaber in my hand. But on the bright side, it leaves my lightsaber sparkling clean.
Just thought I'd mention this because it really does reduce the hassle of having to clean the hilt all the time.
