Vinegar DOES disinfect.
More Info: Vinegar is a form of acetic acid. The vinegar sold in stores has an acetic acid content of 5%. It is this acid that kills bacteria. While vinegar can be a good disinfectant for general household use, it is not strong enough to kill all bacteria. Some benefits of vinegar as a disinfectant include the fact that it is non-toxic, the process of making vinegar is environmentally friendly, and it is inexpensive. Other disinfectants, such as bleach, are very harsh and can burn nasal membranes when inhaled. Vinegar is a gentler alternative.
