Use a gentle or delicate cycle on your washing machine. Set the water temperature to cold or lukewarm. Hot water can cause shrinkage or damage to the fabric.

Use a mild detergent. Avoid using bleach or fabric softeners, especially on polyester blends, as they can damage the fibers.

Turn the t-shirt inside out before placing it in the washing machine. This helps preserve the outer design and color.

Air drying is the best option for this blend. Hang the t-shirt on a clothesline or drying rack to air dry. If you use a dryer, use a low or medium heat setting to avoid excessive shrinkage. Remove the shirt from the dryer while it's slightly damp to prevent wrinkles and reshape it if necessary.
