For stains on white fabrics, I apply it directly, before washing, dissolved in water to be effective in removing them. When I wash whites, I add a dose along with the detergent to keep their whiteness over time, without greying or yellowing. In both cases, it does its job well.

In the washing machine, it doesn't do anything in the compartment. It only whitens the stains when you make a paste with hot water and leave it on the stain locally. Be careful because it fades colors, like in coral which I tried it on. I would say it is only for stains on white/pastel colors.

And the 1 star was unfairly given. I bought it to wash my little one's clothes, which sometimes come with food sauce from the baby food. On the 60-degree, 4-hour program with 1 scoop and laundry detergent, the stains were exactly the same as before washing. Money wasted

Very good results.

Use in pre-soaking and super-strength washing. The only thing that cleans heavily stained children's clothes from tough stains such as fruit, grass, dried blood, and black marks from asphalt.
