    Kids' T-Shirts Care Tips

    Wondering how to care for organic cotton clothing? With a little TLC, you can keep toddler boy, toddler girl, and older kids' t-shirts looking as good as the day you first bought them.

    Here's how:

    • Spot clean stains ASAP to prevent permanent damage.
    • Wash in cold water (68°F or below) on a gentle cycle.
    • Use a mild, fragrance-free washing detergent. Avoid harsh chemicals like bleach or ammonia.
    • Air dry is best (or tumble dry on a low heat).
    • Store tee shirts in a cool, dry spot and rotate them often to prevent uneven wear and fading.
