Set the variable ‘show-trailing-whitespace’ to highlight it in buffers.
Use the command ‘M-x delete-trailing-whitespace’ to remove all
trailing whitespace from a buffer.

More automatically, the ‘whitespace’ minor mode helps working with
whitespace <URL:http://www.emacswiki.org/emacs/WhiteSpace> and is
included in versions of GNU Emacs from 22 onward.
