I thought they contained lye, which is a base. Can we start throwing vinegar at the Antifa douchebags? It’s acidic.
You can get both acid and lye based drain cleaners. People that try one and when that one doesn’t work then pour the other type down the same stopped up drain can tell you how exciting that can be!

That rings a bell, now that you mention it. So I did a little research. It turns out that some drain cleaners use sodium hydroxide (lye), and some use sulfuric acid instead.
One site mentioned that the sulfuric acid concentration in such cleaners can often be higher than 90%. (wow)
