Wind any squeaking tapes onto a metal reel. Tape baking does not call for high temperatures, but plastic reels may melt, so better safe than sorry.
Place the squeaky tapes onto the center rack of your kitchen oven. Do not turn on the oven at this time. Refrain from packing the oven with tapes. Place the tapes in a single layer to insure they receive even heat.
Place an independent thermometer inside the oven in a place where you can read it through the door. Invest in a thermometer you can read from the outside of the oven if your oven does not have a window.
Set the oven to 120 degrees Fahrenheit.
Bake for 10 to 12 hours, monitoring the independent thermometer to make sure the temperature does not rise or fall more than five degrees during this time. Adjust the temperature as needed.
Turn off the oven and allow the tapes to cool slowly inside.
