And one drains lots of water afterwards less drains are messed up.

I remember when the cast iron pipe that ran overhead in the physics department
split open. Seems that for years a slow and ever present drip of acid from
all work stations (chemistry lab) above us ate the bottom of the pipe out.

Replaced it with Quartz that is really protective.

I'm not a chemist, but I'm pretty sure most drain cleaners are strong
caustics, not acids

There are both lye based as well as sulphuric acid based cleaners.
Your Ace Hardware probably has a bottle of concentrated, 80%, sulfuric
acid, sold as drain cleaner, that you can buy and use as drain
cleaner. It is very serious stuff and works very well. Dissolves human
hair, etc. Such a bottle lives on a shelf in my garage and I can
attest to its efficacy. It converts at least a part of the scum from
drains, into stinky H2S.
