How to Keep Your Heartfur Tee Looking Fresh—Just Like Day One
- Flip it inside out before washing or drying. It’s a small step that makes a big difference.
- Use cold water and mild detergent.
- Skip the heavy spin cycle. Your tee’s been through enough—no need for extra drama.
- Air dry when you can. If you must tumble dry, don’t mix it with bulky stuff like blankets or coats.
- Iron inside out on low heat.
