Boeuf Effect Soap (household soap) - In its pretty box

Soap for laundry, cleaning. Do not use on the skin! The formula has been designed to achieve maximum stain removal capacity. You can use it in 2 different ways, possibly complementary. Rub the bar of soap directly on the stain, the wet fabric, before putting in the machine. The other way is to grate it into flakes, and add it to your laundry, the most effective being to dissolve it in hot water beforehand. You can also soak the laundry overnight in a water bath, with this grated soap and why not baking soda.
