Due to the nature of the process, foil print shirts are more sensitive to washing than most other decoration styles. It tarnishes after washing and may start to flake off slightly after numerous washes. First, turn the shirt inside-out. Next, use a delicate wash cycle, or better yet wash by hand, with cold water and a mild detergent. Hang dry. NEVER tumble dry. Do not iron over foil.
Silver foil is a delicate print and will crack and peel over time. It will last almost as long as a screen printed shirt.
