I just got mine. Here's the EASIEST way to do it...
1.) Get a SOS Brillo pad, wet it a bit. Get some good paper towels/shop towels.
2.) With a helper, start cleaning off the passenger side, front of the axle tube. Clean about 6" out from the pumpkin. The numbers will be stamped at about the 2'o'clock position.
3.) Rub the brillo, then wipe. Continue this method, until it starts getting shiny silver.

I just did this and it worked PERFECTLY! The axle came PERFECTLY clean and the numbers were PERFECTLY legible.
