Please don't.  "drive-by" whitespace changes are annoying IMHO.
Rather use non-nil `show-trailing-whitespace' to avoid adding it.

,----[ <f1> v show-trailing-whitespace RET ]
| show-trailing-whitespace is a variable defined in `frame.el'.
| Its value is nil

| Automatically becomes buffer-local when set in any fashion.

| Documentation:
| *Non-nil means highlight trailing whitespace.
| This is done in the face `trailing-whitespace'.
`----

I use the following...

    (when (facep 'trailing-whitespace)
      (set-face-attribute 'trailing-whitespace nil
    			  :background "pink"))
    (let ((hook (lambda () (setq show-trailing-whitespace t))))
      (mapc (lambda (var) (add-hook var hook))
	    (cons 'lisp-mode-hook
		  '(emacs-lisp-mode-hook change-log-mode-hook))))
    (setq-default show-trailing-whitespace nil)


Bye, Reiner.
