How to Bleach Cotton Yarn


Cotton yarn can be bleached by using packets of a color remover product in a volume of water. The color remover will not damage the yarn like a harsh bleach. The process is completed by using boiling water and a large kettle on the stove top. Many individuals choose to use the washing machine with hot water, but the water may not be hot enough to activate the color remover correctly. Color remover products can be purchased in any retail store that sells dye.

Things You'll Need

  • Color remover product
  • Large kettle
  • Water
  • Stove
  • Colored cotton yarn


  • Fill a large kettle three-fourths full of water. Add the color remover, and place the kettle on the stove. Bring the water to a boil.

  • Place the cotton yarn in the boiling solution. Follow the instructions on the box for the correct boiling time.

  • Strain the yarn while pouring the boiling solution down the drain. Rinse the yarn to remove any left over color removal solution. Hang the yarn to dry.

Tips & Warnings

  • Complete the process a second time if the color does not come completely out of the yarn. This means the concentration of the color remover was not strong enough.
  • Removing yarn color using bleach will damage the fibers within the yarn.
