You can use:

:s/^[0-9]*,[0-9]*,// 

For the whole file, that's:

:%s/^[0-9]*,[0-9]*,//

A good regular expression may be:

/^\(\s*[+-]*[[:digit:]]*\.*[[:digit:]]\+,\s*\)\{2}/

This will match numbers, including an optional sign and an optional decimal point (assuming you use . in your locale) followed by a comma and optional whitespace twice at the beginning of the line.

Usage:

:%s/^\(\s*[+-]*[[:digit:]]*\.*[[:digit:]]\+,\s*\)\{2}//

Add hex digits ([[:xdigit:]]) to taste.
