Step 1: Preparation for colored fabric

Before you begin the process, you must wash and dry your curtains to ensure they are clean. Preparing the solution while the curtains are hanging to dry is simple: combine water with soda ash, dish soap, and a spoonful of all-purpose color remover.

Step 2: Create the mixture

Using a large pot set to high heat, combine all of the ingredients and bring them to a boil. Adjust the heat setting to bring the mixture to a gentle boil after the water has boiled. How much water and other liquids you need to boil depends on the amount of fabric you intend to cook.

Boiling water can be used to soak your curtains for about an hour. If you’re not using a pot to wash your curtains, you’ll need to ensure that the water is hot enough to complete the operation.

Step 3: Color remover treatments

Add an additional 14 teaspoons of color remover to the solution every fifteen minutes while the fabric is simmering in hot water. Stir the mixture to ensure that it is properly distributed throughout the fabric.

Step 4: Draining

To remove the hot water from the curtains, turn off the heat and remove the pot. Rinse it thoroughly before serving. When rinsing the mixture from the curtains, be mindful of the heat that emanates from them. Rinsing them in the washing machine is always a safe option.

Step 5: Bleaching process

Adding extra bleach to your colored curtains will make them lighter in hue. Allow your drapes to soak for at least a couple of hours.
