Please elaborate. All you need is to type the question, no special formatting required. You may need to start a new thread instead of asking in an old one, and you may need to select a correct forum (I would suggest Citizen Chemist), other than that there is nothing special about posting.
Your question was unclear as you have not gave us enough details. Technically it is possible to do what you wanted to do, however, it requires someone trained, equipment that you don't have and finally - it is not worth it, as it is much easier and cheaper to just replace the acid with a fresh one.
