Textile Engineer Question:

Technically speaking, no. Some fabrics and colors can be changed or lightened using a good dose of chlorine bleach. Caveat: Start with a cup of chlorine bleach. Keep in mind that bleach will deteriorate fabric and if you use too much, you may end up with a shredding rag. Dharma also sells a color discharge for removing dye from fabric. If you are willing to be unattached to the outcome, you can try these methods.
