Recovering academic now in public safety. You’ll find me kibitzing on brains (my academic expertise) to critical infrastructure and resilience (current worklife). Also hockey, games, music just because.

  • Most drain cleaners are not acids but bases - same basic idea but the other end of the pH scale. Bleach is an example of a corrosive base you’re probably familiar with. Bases were used because they were more compatible with the solder that connected copper pipes in older homes. For non-corrosive cleaners they fall into a couple classes:

    Fizzy things. These loosen clogs by bubbling them apart. They are typically made by mixing a weak acid with a base - hello vinegar and baking soda! The acid may help a bit with dissolving some clogs. These can take a while

    Enzyme based cleaners. An active enzyme will digest some of the bonds in hair and other components of the clog. These can take hours to be effective so don’t be in a rush.

    Temperature based. Fats often make up a big component of clogs. Something as simple as boiling water can do a lot to loosen up a clog. There are fancier mixtures that will warm up the pipe to try to get things flowing.



  • This really about a definition of “working class”. What’s always interesting to me in these arguments is that it’s a Britishism originally tied to class consciousness more than economic circumstances.

    Vicars, writers and such were examples of “genteel poverty” who were very well educated but still lived a hand-to-mouth existence. They were not considered part of the working class even though they very much had to work, and were often poorer than many tradespeople. Because of education and contact with the well-to-do, those workers had an expanded world view and thus not considered part of the “working class” who were focused on tawdry gossip, when they were going down to the pub, and what was for lunch.
