I mean they’re food safe if they’re used in the espresso machines so I don’t think it’s bad. It’s def not policy, but it works well lol

So it's not the "correct" cleaning routine, however as long as you follow up with the 3 basin sink or dish washer to get all the cafiza off it then it is safe and more effective at getting stains out than the "correct" cleaning procedure.

I’ve seen people use cafizia, urnex and Dezcal on a multitude of things. If things are being cleaned, it’s all right in my book.
