Modern dish soap is not acidic or a base so it’s quite harmless to the patina, but it’s also superfluous because you generally don’t want to degrease the thing which is the only thing that soap is good for. Boiling some plain water in it cleans off anything that you want to get rid off. If you’re terrified of bugs when not using soap for some reason get yourself a bonfire and heat your pan as hot as you want for as long as you want nothing will survive that. Just make sure to not melt it.
Nah this is more reduce a tomato sauce territory.
