Nothing is predictable when it comes to tie dying. Every shirt will have a slightly unusual design, as well as different shades of colors. Salvaging a shirt that did not tie dye will require a little effort on your part to remove the dye. T-shirts made from 100 percent cotton produce the best tie dye effects.

Set the water level of your washing machine to adequately cover the shirt. Run hot water into the washing machine's tub.

Add 1 tbsp. of liquid bleach per gallon of hot water and your favorite laundry detergent. Start the washing cycle and let it run for 2 minutes before putting the shirt into the washer. This will ensure the bleach and detergent are mixed well with the wash water.

Place the shirt into the washer and complete the wash and rinse cycle. Remove the shirt, but do not put it in the dryer.

Dye the entire shirt with a darker shade than previously used, or repeat the tie dye process. If an adequate amount of dye has been removed or faded, dyeing the shirt a second time will cover previous dye.
