I also know that you can put vinegar into the "bath".
I did this with little water, and then put it in a 2nd bath with just a lot of water, then drain.
I am lucky, I do not have this problem now...
I just do not wash my greens!
Some people say that we need things like the formic acid from ants and so on...
I reckon there is some sort of psychological barriers with bugs.
The only only ne I cannot cope with are slugs!
My big victory is to not look at meety fruits any more, except when too much and can be seen from outside.
But I still have to not watch. I assure you there is no taste problem, that is just a matter of changing what was just unthinkable... yuk and cheers! Salud!
