I can recommend to put the following into your .emacs

  (add-hook 'lisp-mode-hook
            #'(lambda ()
                (setq whitespace-style 'color)
                (setq whitespace-chars '(trailing indentation))
                (whitespace-mode 1)))

and Emacs will colorize offending places.
