Has anyone ever used white vinegar or baking soda to clean out the grey and/or black tanks?
Nope, mainly because vinegar, baking soda, or hydrogen peroxide won't sanitize, but bleach will. Read this.
At room temperature only bleach will sanitize. Plus, you only need a 50ppm bleach solution (1/4 cup per 15 gal of holding tank capacity).
To sanitize like bleach but using vinegar or hydrogen peroxide, you'd have to heat the liquid to 130 degrees F and use full-strength solutions -- that's 15 gal vinegar or H2O2 per 15 gal holding tank capacity. $$$
Use bleach.
^^^^^^^^^^^^^This is the best answer I've seen so far.
