This sounds kind of sad, but man, I feel like cleaning tips also need to come with a glossary! I'm still in tadpole form, one day I'll grow legs that know how to clean things!

Jokes aside, google is amazing and apparently you can make it out of borax/ sodium bicarbonate/ sea salt, etc (though I've recently learned borax can be unpleasant, but plenty options). The only scouring powder I had used before was of the "wear gloves if you still want skin without chemical burns" variety. I forgot about alternatives. Good to know, thanks!
