NaOH will also do

I’ve found it at supermarket sold as Red Devil drano. It was in a white tall plastic jar with red lid and lettering. Most dranos are liquid with various chemicals, I’ve never tried them. But Red Devil brand is pure NaOH pellets. That worked perfectly for me.

Still no chemicals

Not finding any local stores that carry KOH, perhaps I am looking in the wrong places or I may have to order it online. So I’ll come back to this one and some others when I stop procrastinating.

Chemistry is required to be sure, but good chance you have one of the K+ yellow to orange or red one (I only rarely find any others):

X. cumberlandia — K+ orange
X. lineola — K+ red (somewhat larger on average)
X. stenophylla = X. somloensis — K+ red (mottled white at tips)
X. coloradoensis — K+ red (lobes “tattered” and overlapping in the center)
