What's the most efficient way to repeatedly remove leading text using Vim?

Question

What's the most efficient way to remove the text 2010-04-07 14:25:50,773 DEBUG This is a debug log statement - from a log file like the extract below using Vim?

2010-04-07 14:25:50,772 DEBUG This is a debug log statement - 9,8
2010-04-07 14:25:50,772 DEBUG This is a debug log statement - 1,11
2010-04-07 14:25:50,772 DEBUG This is a debug log statement - 5,2
2010-04-07 14:25:50,772 DEBUG This is a debug log statement - 8,4

This is what the result should look like:

9,8
1,11
5,2
8,4

Note that on this occasion I'm using gVim on Windows, so please don't suggest any UNIX programs which may be better suited to the task—I have to do it using Vim.

You could also use visual block mode to select all the characters you want to delete:

gg        Go to the beginning of the file
Ctrl-v    Enter visual block mode
G         Go to the end of the file
f-        Go to dash
<right>   Go one more to the right
d         Delete the selected block
