Finally I found the right stuff to help getting strong odours out of clothing.
This is especially great if one is an OP Shopper and does not want to smell second hand.
The Wash Soda in general is so easy to use: starting from soaking unpleasant smelling dish cloths in a water-wash Soda mix to adding wash Soda to your washing detergent for more effect of the powder.
My washing smells so much more fresh and this is even noticeable in the wardrobe.
Additionally I just love the option to buy these products in bills from a NZ owned company and get it delivered to home.
