Vinegar WILL work on acid dyes, however acid dyes are never used on cotton anymore. Acid dyes are used on protein fibers...wool, silk, alpaca, etc. Vinegar has NO effect on the fiber reactive dyes used on celulose fibers...cotton, linen, etc. Do the research...the information is not false, it is fact. The choice to use it or not is up to each individual.
