Songs to sing at lunch cleanup

I work with infants, and I have one particular little boy who is INTENSELY pro-music. You can get him to be happy through basically anything we need to do as long as you are singing him a song. I like to try to match the song to what we are doing together and I realized I don't have a good one for when we are wiping hands and face after meals.

Does anybody have a song they sing about that kind of cleaning up? I also just kind of put words to random music when I don't have a song, but would love an ACTUAL song haha
