You can always add a function to one of the org-export-preprocess-... =20=

hooks.
However, if you are not careful, you might remove something like

    #!/bin/sh

    in a source code block, or some normal text where,
    #25 starts a new line by accident.

It may be relatively safe to look for # followed by space, or
lines that have only "#" ad the only nonwhite character on a line.

Something like this might work (untested)

(add-hook
  'org-export-preprocess-before-backend-specifics-hook
  (lambda ()
    (goto-char (point-min))
    (while (re-search-forward "^[ \t]+#\\([ \t]*$\\| .*$\\)\n?" nil t)
      (org-if-unprotected-at (match-beginning 1)
       (replace-match "")))))
