Default Household ingredients pcb etching!!!

This guy seemingly found a way to etch pcbs with more or less standard household ingredients:

…still messing with forces I don’t understand – the formula.

Haven't tried it myself, but am definitely going to! Seems too good to be true.
Maybe people who try it can post their product choices and recipes here.

Spoiler alert: The guy is using rageniv, edixorep and tlas (read backwards).

Did it work ?

Muriatic acid (HCl) and hydrogen peroxide (H2O2) are quite common household ingredients as well. That works very well and is "rechargeable" - i.e. you can oxidize the fluid by bubbling air through it and reuse it nearly indefinitely. Once you're done, mix the fluid with lime (Ca) that you get from the garden department in a hardware store, dry the mixture and dispose of it in regular household waste.

I highly doubt the author's claim that the fluid is safe to dispose of by pouring it down the drain. Copper is actually fairly nasty stuff for living organisms.
