I've seen a lot of references on the Internet stating that vinegar mixed with baking soda is an effective way to disinfect mold, bacteria, etc. I'm skeptical that it has a significant effect because vinegar (and the result of mixing baking soda: sodium acetate) is not a particularly strong acid, and I expect that the acidity is the only disinfectant activity in this mixture.
However, many people tout the magic of vinegar and baking soda as a household cleaner.
Here's a sample quote:
Vinegar, historically, has been reputed to have strong antibacterial properties. One test by Good Housekeeping's microbiologist found that 5% vinegar is 90% effective against mold and 99.9% effective against bacteria,
White distilled vinegar is a popular household cleanser, effective for killing most mold, bacteria, and germs, due to its level of acidity. Cleaning with white distilled vinegar is a smart way to avoid using harsh chemicals. You’ll also be glad to know that it is environmentally friendly and very economical.
Baking soda and vinegar kills all food germs and bacteria including E-coli and salmonella, naturally and safely.
A report from the University of Florida suggests that a mixture vinegar + lemon juice + baking soda results in a statistically significant reduction in tested bacteria, though it appears to be significantly less effective than the other cleaners tested.
