You really should always:
- Gentle handwash with a mild detergent
- Line dry in the shade

But if you're tooo lazy to do that, you'd better:
- Gentle cold wash in the machine with similar colours
- Cool iron on reverse side

Just promise that you'll listen to us when we say:
- No bleach
- No tumble drying
- No dry cleaning
- No leaving me at your ex's house. (We mean it.)
