Question: how long should you leave bleach on clothes for tie dye?
Answer: I let the sweatshirt soak in the bleack solution for about 10 minutes. After that time, I started to see the color change. Tip: Remember that the colors will look lighter after you wash and dry the sweatshirt! For some fabrics, you may want to leave the bleach on for 15 minutes, or even up to 20 minutes.
