Just read a post by Amandha Vollmer on her Telegram channel:
https://t.me/amandhavollmer that I wanted to share here.

So far in my research, oxidation of OH radicals by H+ ions can help to explain why putting out vinegar (acetic acid, as well formic acid seems to be a player) is helpful in dispelling chemtrail clouds. So far in my experiments I notice a complete change in the weather above me, compared to the spraying campaigns that were literally NON STOP daily over my property. Now I see normal cloud formation, more sunny days and blue sky, less white haze, proper rain showers and I barely see any trails at all. I did not get hit hard during the geoengineered “derecho” that damaged many properties (not one tree fell and nor was there any damage to my friend’s properties that had their vinegar out). 

It seems there is an acid-base chain reaction effect that occurs via evaporation which can show you how subtle local hydrogen ionic (H+) changes can affect water. I now have my humidifier so I will move from passive evaporation to more active vinegar output and see what occurs.

Feel free to experiment and report your findings!
