How to wash wool sweaters ecologically: tips & tricks

Here are some tips for cleaning your wool sweaters in an eco-friendly way:


Use pure Marseille soap (just to rub it gently on the fibers of wool with warm water), or mild soap free of allergens to treat isolated patches. Marseille soap effectively treats different types of dirt and stains and is a highly ecological product.

Liquid detergents

You can buy biodegradable liquid detergents that are phosphate-free, some of which also contain lanolin to soften fabrics and eliminate static electricity. You can also buy soap nuts for laundry that come from the Sapindus Mukorossi plant, for many years they have been used in Nepal and India. The shells of nuts are sold in reusable bags that can be used up to three times (even in the washing machine). Walnuts release saponin in water and are hypoallergenic.

Soft and absorbent towels

You should not wring wool items as they are delicate and this would damage the fibers, it is preferable to dab the excess water with a towel, preferably neutral in color and with a good absorbency. Just lay the sweater on the towel, which must be rolled by pressing gently to remove water.

Using steam can remove wrinkles and odors from a sweater. Hang the clothes in the shower or over the bath and leave a bowl very hot water or heat a pot of boiling water and put it under the clothesline.

Lavender and Cedar

Last, remember that you can always protect your clothes from moths avoiding the use of chemicals by simply using some small tricks like scented sachets of lavender and cedar wood cubes arranged in closets and drawers.

Remember: measure! It is a good idea to take the measurements before washing, in order not to end up with a shirt two sizes too big. In this way, just lay the garment after washing, making sure you stretch it to the correct size so it is its original size when dry.
