How to Wash Your Express 1MX Shirt: Step-by-Step Guide
Express 1MX shirts are easy to care for and can be machine-washed and tumble-dried. Here are the recommended methods for washing your shirt.
Machine Wash in Cold Cycle

Cold washing at 30-40°C (86-104°F) preserves the shirt’s dimensions and prevents thermal shrinkage in preshrunk cotton. A gentle cycle reduces mechanical action that can cause fabric stress and wrinkle formation.
Steps
- Add 1-2 tablespoons (15-30ml) of mild liquid detergent to the washing machine dispenser.
- Set the cycle to cold (30-40°C/86-104°F) and select the gentle or delicate setting.
- Wash the shirt with similar colors on the gentle cycle for 10-15 minutes.
- Tumble dry on low heat (max 50°C/122°F) or hang to dry.
Hand Wash in Cold Water

Hand washing provides the gentlest cleaning for delicate fabrics. This method minimizes mechanical stress and is ideal for maintaining the shirt’s pristine condition.
Steps
- Fill a basin with 4-5 liters (1-1.3 gallons) of cold water at 30-40°C (86-104°F).
- Add 1 teaspoon (5ml) of mild liquid detergent and agitate to create suds.
- Submerge the shirt and soak for 5-10 minutes.
- Gently agitate the water with your hands for 2-3 minutes.
- Rinse thoroughly with cold water until all detergent is removed.
- Press gently to remove excess water—never wring—and hang or lay flat to dry.
Tips for Caring for Your Express 1MX Shirt
- Always follow the care instructions on the shirt’s label.
- For stubborn stains, pretreat with a stain remover before washing. Consult our stain removal guide for specific treatment recommendations.
- Never use bleach or harsh chemicals. These degrade cotton fibers at a pH above 11 and cause permanent fabric damage and color fading.
- If ironing is necessary, use a low setting (max 150°C/302°F) and iron inside-out. Avoid ironing directly over buttons or embellishments.
- Hang your shirt to dry whenever possible. This prevents heat damage and reduces wrinkles by up to 80% compared to tumble drying.
- Store shirts on padded hangers to maintain shoulder shape. See our cleaning glossary for more garment care terminology.
