I inferred a trick from his original video. Dish soap and dishwasher detergent are not the same; the latter contains an enzyme that breaks food down. If you have something that is completely wrecked, fill it with piping hot water and put a dose of dishwasher detergent in it. Leave it overnight.

I strongly doubt the stuff is good for your skin, so I've only done this a few times.

This works for cleaning a lot of things. I regularly clean the coffee maker (a Bialetti espresso thing) by putting some powder detergent in the water compartment, then „make coffee“ without actual coffee and leave it in overnight. Neutralize with white vinegar (which has the added benefit of descaling) and rinse thoroughly. It‘s as new afterwards.

And yes, it’s not good for your skin, so avoid immersing your hands in it or wear gloves.

Depending on what thing you’re talking about, often the easiest way to clean various pans is to just fill them with water and bring them to a boil for a few minutes
