Help! I have a medium sized seashell stuck in the drain pipe of my host’s shower. What can I do to get it out or dissolve it?

-Rosana

Rosana, dissolving a seashell takes a powerful acid, such as hydrocloric acid (HCL), which can damage (and even eat through) the pipe metal. If it can’t be pulled out then it may have to be broken apart. The bottom line is that you don’t want to make this worse, I would recommend telling your host about the seashell and maybe offering to help him/her remove it or help pay for a plumber to come out.
