Printed apparel can be machine-washed cold, inside-out on a gentle cycle with a mild detergent and like colors. Use non-chlorine bleach only when necessary. You shouldn't use any fabric softeners, or dry-clean the items.
DTG-printed apparel can be tumble-dried on a low cycle, but hang dry works best.
When it comes to ironing, use cool iron inside-out. Do not iron the print.
Embroidered shirts also can be machine-washed cold and inside-out on a gentle cycle with a mild detergent and similar colors. You can use a small amount of chlorine bleach, but non-chlorine is the safer option. If you notice any color residue in water, rinse the garment in lukewarm water and then in cold several times, but try not to rub any stained embroidery. Embroidered clothing can also be dry-cleaned.
After washing, don't leave the clothing soaking, or lying in a pile while wet. Do not wring out the embroidered articles, but if you want to tumble-dry them, use a cool air setting.
If the garment needs ironing, do it inside-out, preferably between two pieces of cloth. You shouldn't wet embroidery before ironing or use a steam iron.
