I once had this problem in the lab. I put some NaOH (I guess it can be found in some bleaches or cleaning supplies for declogging pipes) and water in it. It warms in the process, but it's not a problem. After an hour or so, and after bit of scrachingscratching (watch out, the brush might decompose in such basic solution), sulphurthe sulfur was gone.
