Step-By-Step Guide On How to Bleach a Shirt For Sublimation

  1. Step 1: 

Put on rubber gloves and protective eyewear. Bleach can be very harmful to your skin and eyes, so it is important to take precautions before starting.

  1. Step 2: 

Mix bleach and water in a ratio of 1:1. If you are using a spray bottle, make sure to shake it well so that the bleach is evenly mixed with the water.

  1. Step 3: 

Test the bleaching solution on a small area of the shirt to make sure that it will not damage the fabric. To do this, simply apply a small amount of the solution to an inconspicuous area of the shirt and wait a few minutes to see how it reacts.

  1. Step 4: 

If you are satisfied with the results of the test, begin bleaching the entire shirt. You can either soak the shirt in the bleaching solution or use the spray bottle to apply the solution to the fabric.

  1. Step 5: 

Allow the shirt to soak in the bleaching solution for at least 30 minutes. You may need to leave it longer if you want a more dramatic effect.

  1. Step 6: 

Rinse the shirt thoroughly with water to remove the bleach. If there are any stubborn stains, you can try scrubbing them with an old toothbrush.

  1. Step 7: 

Wash the shirt in your washing machine using the hottest water setting. This will help to remove any residual bleach from the fabric.

Safety Tips

-Never mix bleach with ammonia or any other cleaning products. This can create a toxic gas that can be very harmful to your health.

-Make sure to ventilate the area where you are bleaching the shirt. Bleach can produce harmful fumes, so it is important to open a window or door if possible.

-Never leave the bleach on the fabric for more than 30 minutes. Doing so can damage the fabric and may cause it to fall apart.



Q: Can I use any type of bleach?

A: No, you should only use chlorine-based bleach for this project. Do not use an oxygen-based bleach, as it will not work properly.

Q: How long should I leave the shirt in the bleaching solution?

A: The minimum time is 30 minutes, but you can leave it longer if you want a more dramatic effect.

Q: Can I use this method on other types of fabric?

A: Yes, you can use this method on any type of natural fabric. However, bleaching may damage synthetic fabrics, so it is best to test the solution on a small area first.

Q: Should you bleach before or after sublimation?

A: It is best to bleach the fabric before you print your design. This will help to ensure that the colors are bright and vibrant. If you bleach the shirt after sublimation, the colors may not be as bold.
