Leviticus 13:54-56

Evangelical Heritage Version

⁵⁴ the priest shall command that the material with the contamination on it is to be washed, and he shall quarantine it for seven days a second time. ⁵⁵ Then after the contaminated material has been laundered, and the priest examines it, even if he discovers that the contamination has not changed its appearance and the contamination has not spread, it is unclean. You must burn it in fire, whether the rot is on its front or its back. ⁵⁶ But if the priest examines it and discovers that the contamination has faded after it has been washed, he shall tear it out of the clothing or the leather or the warp or the woof.
