English 101

I posted this photo today before I realized I had left my face as clean as a ...what is a good analogy for "clean"?  I went into that sentence with "as a baby's bum" on my mind, but you can see why I hesitate.  The posting was to celebrate the excellent work my cousin Joan did on making me a rainbow bracelet to replace the plasticky rainbow band I had which is making my skin somewhat scratchy, like the last scritch of a mosquito bite.  Now, there's an analogy.

I used to be really good at finding analogies, but since the initial word I'm looking for sometimes evades me, I don't try as hard as I used to to, which is good because I just looked up "analogy" and find I was using the wrong word for the thing I was trying to explain:
