Let God clean your heart first. Your works will not clean you. Only the blood of Jesus cleans you from the inside out.

So Go to you room, close the door and be alone with God in that intimate place. He will clean you and it will overflow to your works also.

Matthew 23:25,26 ~ "Woe to you, teachers of the law and Pharisees, you hypocrites! You clean the outside of the cup and dish, but inside they are full of greed and self-indulgence. Blind Pharisee! First clean the inside of the cup and dish, and then the outside also will be clean.
