How can I apply this function to all my sour

If you want to mark the source files in a dired buffer and then run a function to format each you can do something like this:

(defun clean-file(filename)
  (your-function-goes-here))

(defun clean-each-dired-marked-file() 
  (interactive)
  (for-each-dired-marked-file 'clean-file))

(defun for-each-dired-marked-file(fn)
 "Do stuff for each marked file, only works in dired window"
 (interactive)
 (if (eq major-mode 'dired-mode)
     (let ((filenames (dired-get-marked-files)))
       (mapcar fn filenames))
   (error (format "Not a Dired buffer \(%s\)" major-mode))))
