@rockinkranch The concentration of acetic acid you are recommending is not sufficient to kill mycobacteria.
Household vinegar is 5-6% acetic acid, and must be used full-strength for 30 minutes to be effective according to studies. If you are dealing with M. abscessus you need a 10% solution.

Therefore, if you plan to disinfect with vinegar, get 6% (read the label because cheaper white vinegars are only 4-5% acetic acid) and soak in full strength household vinegar for 30 minutes.
To limit the amount of plastic waste I generate, I buy 30% acetic acid and dilute 1 part vinegar/4 parts water or 45% acetic acid and dilute 1 part vinegar/6 parts water to get a 6% concentration. (90% is also available (dilute 1:14), but it is very corrosive if spilled and harder to find.)
