I have used three different file erasers. I like the way Mutilate File Wiper works but it takes less than half the time to wipe a file 3 times than Window Washers. Sneaky Clean claims to do the best and is quite expensive. What can you contribute to comparisons and the question of how to tell that they have really done the job?
