To clean your face, all you need is soap and water.
To get "clean" in God's eyes can only be done one way. It is the only way to avoid an eternity in the torments of Hell. I recommed you get a Bible. Start with the nutshell version. Read the book of Romans chapter 10, verses 9 & 10. Do it quickly, ASAP. Eternity is only a heartbeat away, no matter how fit or healthy you are. Once you have that under your belt, read the books of Genesis and Exodus (at least chapter 20) then the Gospel of John. Thats a good start anyway.
