A processor receives one or more temperature readings from one or more sensors disposed in a substrate processing chamber. The processor determines a peak for each temperature reading from the one or more temperature readings, which indicate an end of exothermic film clean reaction. Upon determining that each temperature reading has peaked, the process issues a notification to cease the cleaning process.
