As you can read in subparagraph six, Chapter 26, page 4,895 (Methods for Polishing the Talons of your Superb Owl Statuette), it is clearly stated that in lieu of Mr. Clean, one may utilize Virgin Ox Blood, as the Superb Owl is known to favor unspoiled Oxen from time to time. Simply track down an Ox, check for its virginity in the normal manner, and tie it up with the other virgins using the rope you should have constructed from the intestines of a fell'd GreatWurm.

It would be wise of you to doll up your Oxen with peacock feathers -- Eli Manning and Ray Lewis have both used this method to curry the favor of the Superb Owl. Tom Brady did it twice, each time using a total of six (6) Oxen, the remaining four virgins aiding the beasts in arranging a visual tableau inspired by the works of the great bard Shakespeare*. In all cases, these men were awarded the title of Most Valuable Sacrificier by the Superb Owl himself, and were gifted a cart of a thousand gilded field mice, which they then pawned for rings of power.

*There is some irony to this, as Manning decided to have the women playing the male roles with the oxen playing the female roles; in Shakespeare's time, as you may remember, the female roles were played by males, while the ox roles were played by mechanical horses.
