In order to avoid the usual pitfalls, you can boil your spoon in a larger pot of water. This keeps the spoon from not having enough space to move around freely.
To keep damage risks minimal, only allow the spoon to remain in the pot for 5 minutes. As soon as the process is complete, remove the spoon from the pot and give it the chance to cool off completely. Dry it off with a clean towel and you are good to go. Check out the video below:
You can also hand wash the spoon with warm water and use a vinegar solution in order to keep it fully disinfected. For best results, create a solution that is equal parts white vinegar and water. Oil should be applied regularly as well and baking soda works wonder for the truly stubborn stains.
