How to Dye Over Yellow Bleach Stains on a Wool Sweater

It is always disappointing when bleach drips onto anything, especially an article of clothing such as a wool sweater. Although the stain cannot be removed, the sweater can be dyed any color darker than the bleach stain. When dyeing wool, it is important to handle it gently as the fibers can become matted and pill if they are rubbed together.

Instructions

- 1
  Wet the sweater with cool water and set it aside.
- 2
  Fill your dye pot with enough water for the sweater to float freely in the water; do not add the sweater at this time.
- 3
  Heat the water slowly to the temperature recommended on your dye instructions.
- 4
  Add the amount of dye recommended on the instructions for your particular dye. One rule of thumb is 2 percent to 4 percent of the dry weight of the fabric. So, for a 1 lb. sweater, you would add 1/3 to 2/3 oz. of dye.
- 5
  Add the wet sweater to the dye pot and keep the temperature just below boiling, about 180 to 200 degrees Fahrenheit. Periodically check the temperature using your thermometer.
- 6
  Add ¼ cup of vinegar to the water; don't pour the vinegar directly on the sweater as it may cause uneven dyeing.
- 7
  Gently stir the sweater for the amount of time specified on the instructions. Gradually cool the water and remove the sweater and rinse with Synthrapol and warm water. Synthrapol removes excess dye from the fabric and prevents bleeding onto other garments.
