Very good! Now using eSteem Surfer you should remove all the other stuff as well. It allows to edit posts older than 7 days. If you will do it, I'll remove my flags and would give you some upvotes here on your comments to raise your reputation.

would you explain me how can I do it? I tried but no result.

Yes, sure. Have you installed eSteem Surfer already? You have to log in there using your login and pass from Steemit. Then you can open any of your old posts, scroll to the bottom and see small ✏ pencil button to edit your post.
