The detergent I bought because of an article in a magazine. Since the reviews were consistently positive, I was very curious about the result, and have to say it's worth it. I have washed a pocket and a leather jacket in used look. The bag has not changed much - partly positive, greasy stains remain. However, the leather jacket again looks clean. I think an expensive leather cleaning would also no longer be placed. In any case, I will use this product again.
