Wash your shirt like your grandmother would.

I bypass the mothers' generation, no offense, and I dedicate myself to grandmothers only because they didn't have all the chemical detergents available today.
Washing clothes was a shared event. We'd go together to the river or to the village laundries where the streams were natural washing machines, armed with natural soaps or ash mixed with water, and we'd all sing along to the rhythm of the rubbing of the clothes.
I wonder what the smell of clothes hanging out to dry in the wind and sun.
Romanticism aside, I recommend everyone go back to basics and look for natural detergents that won't harm the environment, our skin, or even fabrics, but that will keep everything in tip-top condition.
We also use the magic washing machine, which I myself love, but with cold water washes and shorter times.
Wash your T-shirt inside out and once it's dry, always iron it inside out, avoiding holding the heat of the iron too long on the print.
A 30-degree wash for 30 minutes will keep the colors and fibers in excellent condition for a long time, so you can wear your favorite T-shirt often.
