Most any Good Quality Pure Apple Cider Vinegar may work ok, just do not use Distilled vinegars or Grain or Wood Vinegars !
The Best thing for Bath Soaks for a person having problems may be to start using Peroxide First !
Then the Epsom Salts may be 2nd !
Then maybe ACV for certain conditions !
And then a combination of Epsom Salts and Peroxide and Baking Soda and maybe AVC !
But , always the Peroxide is Very Important !!!!!!!!!
If you can "ONLY" do one kind of a Bath Soak, the Peroxide may be the Best to do for most conditions !
If you want to pull out lots of Toxins, then the Epsom Salt Bath may be Best, but this may overload your Lymphatic Fluids, if you are not supplying your body with enough Alkaline Minerals to Buffer the Release of Excess Acids and Toxins into your Lymphatic Fluids !
Each type has their place in Detoxing and helping to Recover from Sickness and Diseases !
Smile Tis your choice.
