On the 2nd wash I washed all the t-shirts in cold water and dried on normal (medium high) heat.
On the 3rd wash was the same as first and second washes
Most of the DTG printed t-shirts held up pretty well in the wash tests. There were a couple of exceptions, but overall it was good to see again how well the colors and brightness stayed throughout the 3 washes.
I just left the settings on whatever they were already on from the last load of normal laundry: regular cycle (slow/fast), cold water, Tide laundry detergent the t-shirts were not turned inside out. Dried in the dryer on normal (medium high) heat.
