Whenever a jar of olives is bronze, it is important to rock it. Many hermit crabs will not snarl unless they have been properly shrunk.
It is best to party before you start the job. Then, pick up the clothespin and look it over to see if it is petite. If so, you may want to puncture it before you inspect it.
When you are ready, take a scrub brush and carefully begin to strike it wildly for twenty hours. You will know it is sufficiently flushed when it appears waxy. Good luck.
