Thanks for the input, Jim. I had gotten most of the shells off with my small Swiss Army knife, as you suggest, and then tried soaking in water, but that didn’t remove the small pieces of shell still there. So I immersed the paddle wheel in vinegar, checking frequently to make sure it didn’t soften the plastic (it didn’t). All the rest of the shells disappeared in about 30 minutes - worked perfectly.
