Air out your wool shirts thoroughly after every wear so they can naturally regenerate. The longer your shirt has time to recover, the less frequently you'll need to wash it. This helps to preserve the fabric. Ideally, hang your shirt on a hanger in a well-ventilated spot, whether that's outdoors, in the bathroom, or any other airy room. This way, your shirt stays especially fresh and soft.

Machine washing stresses your wool: water causes the yarn to swell, and friction puts strain on the fabric. Your WOOLDAY products don't need to be washed after every wear – wool takes care of much of the maintenance on its own. Often, simply airing out the textiles is enough. Only when your product is dirty or stained, it is time for a wash. This way, you will preserve the natural softness and beauty of your wool.

Dark wool can permanently bleed color during washing. Therefore, you should wash dark wool items exclusively with other dark wool, and always treat light or white wool separately. This way, every wool item in your wardrobe retains its color and stays beautiful.

Turn your wool clothing inside out before washing so that the delicate, right side of your fabric experiences less friction. This way, the surface remains smooth for longer and keeps its natural shine.

Ensure your Merino wool is well protected during washing – the delicate weaves are especially sensitive. Avoid washing your wool garments together with heavy items like jeans or jackets to prevent unnecessary friction. Remember to zip up all zippers and unfasten all buttons before starting the machine. This way, you safeguard your wool clothing from accidental damage during the wash.

Heating water uses up most of the energy in washing machines. By washing in cold water, you not only save money but also take better care of your wool – ideally, it should be washed cold or at maximum of 30°C (86°F). This rule applies to most other fabrics as well. A lower washing temperature is a clear win for the environment, your electricity bill, and your garments.

To get your WOOLDAYs clean, germ-free, and soft, you don’t need any harsh chemicals. In fact, most detergents, fabric softeners, and fresheners can ruin or permanently damage your wool shirts by attacking the fibers. So, steer clear of them. We recommend using an organic, gentle detergent made specifically for wool – our personal favorite is Sonett.

Our fabrics are slowly knitted and don’t twist, ensuring that your seams stay in place. Still, when hanging your shirt to dry, give it a good shake so the fabric regains its form. Ideally, use the side seams as a guide – if you pull your WOOLDAY there and gently bring it into form, it will never lose its shape.

Give your shirt a gentle air-dry and avoid using the dryer. The high temperatures and mechanical strain in a dryer can damage the fabric and harm the delicate wool. Instead, simply hang your shirt up and let it air dry – this way, the fabric smooths out naturally and you save yourself from having to steam or iron it. Plus, wool dries very quickly, so you won't have to wait long.

If you want to protect your shirts from moths, please keep three things in mind:
• Do not store unwashed T-shirts in your closet.
• If you're storing your shirts for an extended period (longer than two months), pack them in a pillowcase made of linen (or sturdy cotton) or a vacuum-sealed bag to ensure they stay safe.
• Before putting anything back in the closet, hang it out in the sun (dry) for two days.

And finally, add a pleasant scent to your closet with lavender, cedarwood, or peppermint—moths don’t like that. Also, regularly set up a moth trap near your wool items so that the moths don’t go unnoticed.
