Dedicated flame sensor cleaning tool that scrubs the oxide buildup off furnace flame sensor rods. A dirty flame sensor is the #1 reason a furnace lights then shuts off after a few seconds. This tool cleans the rod without removing it from the furnace bracket — much easier than sandpaper or steel wool.
