@imaginaryuncle Welcome! Reading around the world is definitely something I ought to do one day.

@sinituulia Oh yeah, now that you mention it, the buildup of powder residue sounds very much like one of the reasons at least. Thanks for the tips!

And zeolite! My goodness, what a waste of countless tons of perfectly good minerals.

@sinituulia I really ought to switch back to powder detergent—if only to remind myself why I switched away in the first place. There must have been a reason.

At least the liquid detergent I use comes in bottles made of 50 % recycled plastic. That’s something. Still, I’m with you here: down with plastic!
