The secret to sanitation is normal clothes dryers. Get to 160F or more and virtually all pathogens are dead, Jim.
I’m surprised anyone even noticed the poopy pants incident there unless they were so poopy that poop was left after the cycle, or smeared over the top of a top loading washer. And a little Pine Sol or bleach on a rag would solve the residue problem.
OK.
You go wash your clothes in a machine that has recently had feces-smeared garments in it.
Don’t expect a hug from me afterward.
