It's best to spot clean all cloth hats with a damp cloth using cold water, or hand-wash in a sink if necessary. We recommend using plant-based soaps because regular detergents can be toxic for our waterways.
Always let your hat dry naturally. If your hat gets out of shape, you can use steam from a tea kettle to reshape it. Hold the hat in the steam and allow it to soften. You can then reshape your hat to its original shape and then let it cool down before wearing.
Another option to take out wrinkles on the brim is to place a clean rag or old T-shirt over the wrinkled area then iron the area.
The hat arrived spectacularly fast (I'm in Australia) and is everything I could have hoped for. Thank you.
