Marseille soap has no equal when it comes to restoring your clothes to their original immaculate white. Few stubborn stains can resist it! Economical and easy to implement, this tip helps eliminate traces of tomato sauce, coffee, or even fat.
To remove white clothing, follow each of the following steps:
Rub the stain directly with the block of Marseille soap, without wetting it
Let the soap sit in a thick layer for about an hour
Then lather with water and scrub again, possibly using a soft-bristled brush
Wash your white clothing in the machine, without rinsing the Marseille soap first.
