我没接触过 drano，Google 了

Most people are familiar with Drano and what it does, even if they have never had to use it. It is, after all, the most popular chemical drain cleaner that is readily available for purchase.

What most people don’t know, and what catches most people off guard, is how strongly pungent and disagreeable it smells.
