I want to take most of the color out of a section of fabric for a reverse tie-dye effect. The fabric content is 100% flannel cotton, and has been washed and dried by the usual, conventional method. Is there a particular Clorox® Disinfecting Bleach to water ratio I should use, and is there a water temperature that is the most effective? Also, is it possible to use undiluted Clorox® Disinfecting Bleach without destroying the fabric?
Sounds like an interesting art project! First, let me clarify that you should never use full-strength Clorox® Disinfecting Bleach to treat any surface or fabric–it should always be diluted with water first. While it can be tempting to get faster results with bleach art, it can cause holes to develop over time.
Also, be sure to avoid bleaching wool, silk, spandex, mohair, and leather–it’s great that you have picked a 100% cotton fabric instead.
And finally, there are detailed instructions for how to reverse tie dye with bleach that you can check out here.
