How to delete all comments in a selected code section?

Question

Every once in a while, my code gets littered with many useless comments, most of them are obsolete lines of code, and some are obsolete "memos to self".
So I was wondering if there's a way to just select a code section, and with some magic key combination or macro, delete all of those.

Thanks.

Remove all spaces before the comments too.

(\t+|\s+|\r\n)((/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)|(//.*))
