Here are some of the things to take note of when washing them.
TURN T-SHIRT INSIDE OUT
Turning your t-shirt inside out prevent the prints from being rubbed against violently. This allows the print to retain its vibrancy and help keep theprints from fading.
MACHINE WASH COLD
T-Shirts that contain cotton are sensitive to heat and tends to go out of shape when exposed to high heat.
IRON INSIDE OUT
Ironing on the prints will cause the inks to melt and crack easily. Ironing on Transfer Prints will also cause the glue that holds the image to your t-shirt to melt. If you need to iron your t-shirt, always turn it inside so that you are ironing on the reversed side of the printing.
TUMBLE DRY LOW
T-shirts can get damaged by going expanding and shrinking when exposed to high heat. Drying your t-shirt on a high setting might also melt the fibers in the t-shirt. Always set your dryer on a low temperature when drying them.
