the screen on the MFD in the Prius was getting all fingerprinted and I wanted to clean them off and your not supposed to use cleaning agents or sprays on it, so today I was at FutrueShop, read CompUSA or any number of computer and electronic stores and bought a product made primarily for cleaning Palms or laptops etc. Its a Kensington product called Screen Guardian and there are two cloths per package and it wiped the finger prints off in a single pass. It's a small funny feeling cloth and is washable and reuasble. About $10 tax in. The model number is 12172
