Pre-washing is recommended.
Pre wash in cold water on a gentle cycle
Add a tablespooon of salt to the wash - this helps seal the colour within the fabric thus reducing fading.
Add 1/2 cup of white vinegar to the rinse cycle. the liquid will freshen up your laundry and help colours maintain their intensity.
Dryer use is not recommended - as the heat will eventually cause fabrics to fade.
Line dry without delay - inside out, away from direct sunlight
