Chemicals are what they are. While they clean a garment, they also take away the good stuff. Use minimal detergent and no bleach. Avoid putting detergent directly on the fabric, that can leave spots. Dry cleaning is extreme; your March Tee does not need that.

Iron on hot while the tee is still damp. The neck rib is the most delicate part of the tee; iron carefully without stretching. Use a lint roller on solid tees so that they continue to look new.
