This is version that works. I can interchange (any whitespace) with
(any blank), but none of them recognizes "\n" as whitespace so far.

(defun rcd-string-clean-whitespace (s)
  "Return trimmed string S after cleaning whitespaces."
  (replace-regexp-in-string 
   (rx (one-or-more (or "\n" (any whitespace))))
   " "
   (string-trim s)))
