For those wondering, ′′ how did i do it?":
I Boiled 10l of water, added 2 tablespoons of vinegar, 1 teaspoon of sodium bicarbonate, two cups of coke and half cup of lemon juice then stirred well .
Waited 3 minutes, put the pan in the solution for 45 minutes, then added a quarter cup of chlorine bleach to the mixture.
Then I brushed it with a firm toothbrush and put it back into the liquid for another 25 minutes.
I took it out, rinsed it and it looked exactly the same, so I threw it away and went out and bought a new one.
@ktdoggett that's a lot of work. Cool if I just use my angle grinder instead? 👍
@Sramaroid @ktdoggett have been known to use mine (with wire brush attachment) for kitchen utensils, parts of the stove etc...

Actually, you know what would really work?
A pressure washer.
Not practical for home kitchens, I know, but what about a discrete enclosed unit?
I mean, people use pressure COOKERS, which are potentially deadly.
