I just clean it with soap and water. When there is boiling water, I do tend to stick it in there (not sure why). And, when I grill, I stick the tip near the burner until the temp reads over 160. I know I don't follow all the food safety information out there, but I don't use the same cutting board for raw meat as I do for other cutting and I keep my tools rinsed off and my hands clean - that's about it. Never had a food illness or know of anyone getting sick from my food. I just think the basics go a long way and the rest is overkill.
