How to Bleach a Shirt for Sublimation
This quick step by step tutorial will show you how to bleach a shirt in the sun to prepare it for sublimation or heat transfer vinyl.
Lay your sweatshirt outside in direct sunlight.
Mix together a ratio of 50% water + 50% bleach (that's 1:1). Put in a spray bottle.
Spray onto your sweatshirt. I put a heavy amount on it due to the thickness.
Leave your sweatshirt in the sun and allow the bleach to work its way through the fabric.
It will continue to lighten in the sunlight.
When you are satisfied with the color, you will want to stop the bleaching process.
To stop the bleaching process (using gloves) place the sweatshirt into a container that has 50% water + 50% hydrogen peroxide.
Wash the sweatshirt.
Now it's ready to press your sublimated design right onto the bleached area.
