Yes, there are hooks: `emacs-startup-hook' - but isn't
this something that should rather go into
`find-file-hook' or perhaps `before-save-hook'?

Because if you use the Emacs startup hook, won't you
get the same situation whenever you `find-file' or the
like from Emacs, i.e., whenever you don't open files by
means of arguments to the emacs shell command?

Anyway, for example, I have

(untab-all delete-trailing-whitespace)

as `before-save-hook'. You could put a call there to
the function that removes those chars.

Hooks are a often an efficient-but-still poor-man's
solution. If you can do something without using them,
that is often better. In this case I can't tell. But if
there isn't an obvious better way to do it, sure, use
hooks.
