Hol up… You’re supposed to heat the plunger up first? I can only assume it’s to loosen up the rubber so it compresses better, but I’ve never felt like it was too stiff to not work.
This was the part that I wouldn’t do just because I view the sink as mostly clean and plunger as mostly dirty. So unless I were to sterilize the sink afterwards I wouldn’t put a plunger in the sink.
Yeah seriously that’s gross as fuck. I wouldn’t even want to use a garage sink to rinse a plunger. It’s just too nasty for me. It gets rinsed outside with the hose.
