Care InstructionsHere are some ways you can look after your custom printed T-shirt to keep it looking & feeling great:

- Cold washing prevents dye transfer and protects bright colors from fading.
- Cold washing is suitable for lightly to moderately soiled items.
- Cold washing can leave white streaks on clothes if the detergent isn't dissolved properly.
- Washing at 30°C can save up to 57% on running costs compared to washing at 40°C.
- Gentle cycle with mild detergent and similar colors.
- Use non-chlorine bleach, only when necessary.
- No fabric softeners.
- Tumble drying on low or hang-drying in air is suitable.
