I've been cleaning all of my samples from last summer. The idea is to get all the organic gunk out, because all I want to analyze is the chemistry of the shell, not the chemistry of the other stuff. This translates to a lot of sitting very still and working with very tiny things.
The cleaning process happens at 65ºC, which takes a while to stabilize.

| Not quite at 65ºC. Yet. |
I can't emphasize how tiny each sample is. I keep them in little microscope slides with 10 wells (each sample gets its own well. They are really small.
 |
| This is my entire summer's worth of work. |
Each one is the size of a grain of sand. You pick them up with a tiny paintbrush, the kind you might use to paint the facial expression on a tiny model man standing on the deck of a ship built inside of a bottle.

| My brush is named Otis. |

| Then I crack each shell open with the point of a scalpel. |
I was pretty impressed by all the cytoplasm and other ... well, organic goo that was inside of some of them. So I literally peroxided the snot out of them, and now they're clean. I scavenged some foam from a buddy and built a little foam raft so the samples could ride on the 65ºC bath. I'm sure Fisher Scientific has a version for sale for $30, but mine works just fine.
