Vinegar releases acetic acid into the air. From the Occupational Health Guideline for Acetic Acid: “Acetic acid vapors cause irritation of the eyes, nose, throat, and lungs. Inhalation of concentrated vapors may cause serious damage to the lining of the nose, throat and lungs. Delayed breathing difficulties can occur.” This is especially important information to know if you have a baby or young children, are elderly, or someone in the household that has asthma, bronchitis, or chronic illness etc. as they are more vulnerable to this irritant.
In addition if a lot of vinegar is used for cleaning and there is not proper ventilation, over time the acetic acid will corrode soft metals like copper and brass and can cause problems with the HVAC system as the acetic acid passes through the air ducts.
But for vinegar and water users, not to fret! This is a much better alternative than most “green” cleaners. The caveat comes down to how you use it. If vinegar is used, it’s best to ventilate and avoid enclosed spaces as the fumes can build up and potentially irritate lungs, especially those of the little ones and immune compromised.

I haven’t heard of that one. I will check it out! Thanks!
