Just a reminder that when taking an ammonia bath only use 1-3 caps of ammonia. How much you use is up to you and depends upon how much negativity one has on them. Ammonia will strip away everything, the good and the bad, so use it sparingly.
When using vinegar approach it the same as with ammonia. Using too much vinegar will sour your life.
I was also taught that Asafoetida has the same property, that it will strip everything so you may want to use caution with it when using it for cleansing/uncrossing.
