I want to make a functional equivalent to this: https://prowin.net/de/produkt/backofen-und-grillreiniger

It's a hard base soap that you paint on the blackish-brownish residue that builds up on surfaces that are exposed to heat and fat. Works great but is expensive as frig!

Want to make my own and already have the KOH, glycerine is on order.

Has anyone ever done did this and has tips on the process side of things?

Excellent reply and great in depth info! I thought the glycerin was a prerequisite for making any kind of soap. Ideally, I'd like it to have a gel like consistency so it sticks to and stays on vertical surfaces. I guess that's what the copolymer in the store bought stuff is for. It is meant to be brushed on. Anything organic like pectin will probably be broken down instantly by the KOH, more research seems to be in order.

Thank you and Mrs. Duck :)

At it's simplest, soap can be made with a fat and caustic. Glycerin is a fat and will work, but you can also use lard, beef tallow, coconut oil, olive oil, cocoa butter - or the baked on greasy crap in your oven or on your stove top. Try using a little KOH solution on a rag for starters. You may find you need a thickener to get it to stick to vertical surfaces and soak in, but it should at least start to loosen and maybe remove the built up crud if you add a little pressure while wiping it.
